MacBook Pro 13in (2015) review



if you want to buy laptop this is the perfect chose.  this is the most advanced of all of Apple’s laptops with price of £1,000

METAL Laptop

To MacBook veterans out there, the 2015 MacBook Pro 13 will look incredibly familiar, though. Apple hasn’t fiddled with the outer design at all. You still get an aluminium casing that looks great and weighs in at a fairly shoulder-friendly 1.56kg. It’s 18mm thick, which is only 1mm chunkier than the MacBook Air at its thickest point.
However, its silhouette is quite different. Where the MacBook Air and 12-inch MacBook are wafer-thin wedges, the MacBook Pro is quite brick-like. It’s roughly the same thickness all the way across, so while it’s still portable, it doesn’t have the excitingly thin feel of Apple’s other laptops.
If you really must show off, you probably want to wait for the 12-inch MacBook. Shove it in a rucksack, though, and the differences start to fade. I’ve been out and about every day with the MacBook Pro for a while now, and you’d barely know it’s there a lot of the time. There are slimmer laptops, but this one is more than slim enough for most, given its other benefits.

THE CLICK TRACK

You might be left thinking: so what’s different to last year’s model? The main change aside from the usual annual power updates is in the trackpad. It looks the same, but is very different inside. Last year, the MacBook Pro used a tilting mechanism, like just about every laptop trackpad. The panel moved on a hinge at the top, getting you that recognisable motion, which was emphasised with a software-managed ‘click’ at the end.
It has been the norm for years, taken for granted. But Apple has changed things up. In the 2015 MacBook Pro, Apple has done away with the hinge movement, relying entirely on haptic feedback. Not only does this mean you can press down on the whole pad with zero dead zone, it also enables a neat new pressure sensitive feature.
The trackpad knows not just when you’re tapping, but how hard too. Press down harder and you’ll get a second, deeper click that’s already used for secondary functions in a bunch of Apple apps. For example, in Safari it’ll bring up web link previews that you can even scroll through. Is it going to change your life? Probably not.
But when every app developer under the sun starts using it, we’ll all be wondering how we got by without it in the first place. Most importantly: it just feels right. The keyboard is much the same. It doesn’t use the fancy (but contentious) new butterfly mechanism you may have heard about, as used in the 12-inch MacBook. Apple has altered the keyboard backlight a bit, but you’d honestly be hard-pressed to notice.
Still, as ever the keyboard is great, full-size and comfy enough to tap out novels on.

INTELLIGENCE

The other deep and meaningful change for 2015 is the MacBook Pro 13’s processor. Last year the Pro used Haswell processors, and now they’ve been upgraded to Broadwell. These are generations in Intel’s Core series, and supply the Pro troupe with far more power than the new 12-inch MacBook, which uses an Intel M CPU.
Every Pro comes with at least 8GB RAM these days, and a Core i5 or i7 CPU. While the chipsets aren’t quite as all-guns-blazing as you might see on a desktop that’s always going to be plugged in, each and every configuration has enough power for video editing, music production and pretty serious Photoshop hijinx. They’re capable computers.
This year’s class doesn’t come with a gigantic performance boost, but our tests show that we’re looking at about a 10-15 per cent boost over last year. Our Core i5 review sample is certainly very snappy, and most people won’t really need to upgrade to a Core i7 - which is for the best as it's a £250 upgrade. Really, those who need serious muscle should be considering the 15-inch model, as it’s the only one that offers quad-core processors instead of dual-core ones.
The 15-inch MacBook is still stuck with last year’s processors, but its top models pack serious power - just remember the extra size means extra weight means less portability.

GAMING GRAVITAS?


The only element that is still a tiny bit malnourished is gaming. Part of the new Broadwell family is an upgraded Intel Iris 6100 GPU that gets you more grunt than last year’s Iris GPU. And, sure enough, it can handle recent games at low settings and juggle less demanding games such as The Sims 4 with relative ease.
However, if gaming is your life, you’re probably better off buying a Windows gaming laptop or the 15-inch MacBook Pro. Apple hasn’t actually updated the 15-inch models for 2015 yet, but they’re the only ones that can fit in discrete graphics cards. That model will cost you a cool £2000, mind. Keep your expectations in check and all will be fine. Levelling-up to Broadwell comes with a side benefit too.
The MacBook Pro 2015 lasts for up to 10 hours off a charge, up from nine hours in last year’s model. Having used the new version as my main laptop for a week, upgrading from the 2014 one, the difference is definitely noticeable. It’s about that extra security of getting all-day stamina even if you do play a couple of games over your lunch break.
Of course, MacBook Airs are still the reigning kings of battery life. The 13-inch MacBook Air lasts for an incredible 12 hours on light duties.

The new Apple MacBook (2016)

The MacBook (priced between AED 4,399 and 9,899) is notable as the Apple's thinnest and lightest laptop. The MacBook keeps the slim profile of the original thanks to a fanless design, and the Retina Display remains, but this time around there's a Skylake-based Intel Core m5 processor with improved performance.
Though there's plenty to like here, drawbacks include a very limited I/O port selection and a sleek, but shallow keyboard and trackpad that are likely to be uncomfortable for some. The aluminum laptop is now available in four colours including gold (our review unit), silver, space gray, and rose gold (a metallic pink, which is the newest addition).
Physically, not a lot has changed from last year's model. At 0.52 by 11.04 by 7.74 inches (HWD), the MacBook weighs 902-gms, an imperceptible increase that makes it slightly heavier than its predecessor. It fits easily in backpacks and shoulder bags made for 10-inch tablets or 13-inch laptops.

The MacBook should be on your short list if you often find yourself in coach class working on an airline tray table. It can also be your go to machine if you are looking for a capable ultraportable to haul around while on the road.
Also unchanged are the butterfly-switch keyboard and Force Touch trackpad. Both are less comfortable than traditional laptop keyboard and trackpads, since the keys offer very little travel, and the trackpad doesn't move at all. Though, Haptic feedback vibrations on the trackpad make it feel like you've clicked, and the sensor can detect pressure, so if you press a little harder, the touchpad will click a second time, and activate the Force Click function. In practice, it does feel like two separate physical clicks.
You can use the Force Touch trackpad's pressure-sensitivity for signing your name on the trackpad, or to vary fast-forward or zoom speeds in programs like QuickTime Player or Apple Maps. The shallow, but clicky keyboard is tolerable for extended typing sessions, but traditional keyboards are more forgiving on your fingertips.
USB-C adoption has improved since the MacBook was introduced last year. Apple now offers a USB-C-to-Lightning cable so you can sync your iPhone to your MacBook. Because there's still only one IO port on the laptop, you'll have to unplug the AC adapter to do so, however. You'll also need a USB-C-to-USB-3.0 cable for most other peripherals, including connecting a USB SSD or flash drive.
USB-C-to-DisplayPort and USB-C-to-Ethernet cables are available from third-party companies such as Belkin and Monoprice. Cables aren't included, so you'll have to budget for them. If you're considering a MacBook, you'll have to decide if the sleek design is worth the inconvenience of the single port and required adapters.
Also disappointing, Thunderbolt 3 support still isn't built into the MacBook. That means you won't be able to use your legacy Thunderbolt and Thunderbolt 2 drives here, even if an adapter is available. New Thunderbolt 3 drives that are just coming to market are also a no-go. The only other physical port on the laptop is a 3.5mm headset jack on the left side.
For wireless connectivity, the MacBook integrates 802.11ac Wi-Fi and Bluetooth 4.0. The 12-inch IPS screen is a bright point. Its 2,304-by-1,440 resolution isn't quite as expansive as the 4K (3,180 by 2,160) screens on some systems on the market. However, text and graphics are displayed smoothly with sharp outlines and vivid detail.
1080p and scaled-down 4K videos looked excellent and played back without a hint of stutter in my testing. The speakers, located just above the keyboard, are loud and clear, which is rare in such a thin system. Inside, there's 8GB of memory and a 512GB Flash Storage module (Apple's way of saying solid-state drive or SSD).
The MacBook's flash storage, memory, and CPU aren't upgradable after purchase, so you'll want to think in terms of future proofing. Apple covers the system with a one-year standard warranty. An upgraded Intel Core m5-6Y54 processor with integrated Intel HD Graphics 515 powers the laptop and helps maintain the thin profile.
The Core m5 processor is cooled without a fan, allowing the remaining space inside the chassis to be filled with more battery packs. As we continue to test more Core-M-equipped laptops and tablets, we're seeing that they perform almost, but not quite as fast as, Intel Core i5-powered systems.
Mac laptops can't run our PCMark and 3DMark benchmarks, so we couldn't compare those scores with PC counterparts. The system took 2 minutes 55 seconds to complete the Handbrake video encoder test and 5:17 for the Adobe Photoshop CS6 test. That's an improvement over last year's MacBook (3:39 on Handbrake; 5:24 on CS6).
The new MacBook's 3D scores on the Valley test were better (15 frames per second (fps) on Medium quality; 6fps on Ultra quality) than last year's model (9fps on Medium; 4fps on Ultra), which shows the improvement of Intel HD Graphics 515 over the older HD Graphics 5300.
Recent Macs have been battery champs, and the new MacBook is no exception, returning an excellent 11 hours 37 minutes on our rundown test. That's 27 minutes longer than the MacBook Pro. You can run the new MacBook on a long flight, with a recharge needed for juice for the return trip.
Aside from the new Rose Gold option, the new MacBook is visibly unchanged from last year's model, though its new Skylake-based processor improves benchmark performance a bit. But battery life takes a hit due to that faster CPU. You can't deny the sleek design, but connectivity compromises you'll have to make may be deal breakers, particularly the single USB-C port and shallow keyboard.
If these drawbacks are show stoppers, and you still want an Apple laptop, the MacBook Pro 13-inch, though not as slim, offers more versatile connectivity and will likely be a better choice. However, if you need a very very slim and light ultraportable that can do all the jobs you would ever want to throw at a laptop, while on the road, the Apple MacBook (2016) should definitely be on you shortlist

Who Invented the Laptop ?

the first laptop


The laptop computer revolutionized the way people work and travel nearly as much as the 
original computer did. Alan Kay, who worked for Xerox PARC, first created the concept for the laptop computer. He referred to it as the Dynabook. Xerox PARC did come up with a working model of the Xerox Notetaker in 1976, but it was not available to the public.
The current folding clamshell design was first used in 1982.
The first laptop computer available to the public was the Osborne 1. The Osborne Computer Corporation released this model in 1981. It cost $1795 at the time of release. The screen was five inches long and the keyboard was in the lid of the computer. (The screen of the Eee netbook pictured here is not much bigger!) It did not have a battery and was quite heavy. A portable battery was designed and available for purchase after its first release. Most of the early “portable” computers weighed about twenty-five pounds. Many of the early laptops were called luggables because they were so heavy!
Netbooks are the smallest consumer laptops yet and offer unprecedented portability.
Since the Osborne 1, the laptop has changed over the years. Innovations to desktop computers eventually trickled down to laptops as well. The first laptop to be comfortably lap-sized was the Epson HX 20, which became widely available in 1983. It was powered by batteries and included a small printer. Better batteries were able to reduce the weight of the computers. The current folding clamshell design was first used in 1982.

Laptops have grown smaller over the years as technology and storage capabilities have improved. Laptops now come with DVD burners and CD-ROM drives, which make it much easier to store and access information. There is a variety of laptops to choose from depending on your needs. Laptops were first marketed to a specific niche market, such as accountants and the military. Soon there will be more laptops on the market than desktop computers. Additionally, many different professions use laptops. They are especially useful in making presentations and in helping business people as they travel, since they can rent a projector to accompany their own laptops or, vice versa,rent laptops to match the built-in projectors found in many meeting spaces today. The general universality of laptops (except Mac laptops, which have adapters) means the equipment you choose will be simple to connect.
There are many types of laptops available to consumers. Some laptops are designed as a replacement for a desktop computer and these come with a larger screen and more memory. Other laptops are designed with portability in mind. These computers tend to be smaller and have a smaller amount of memory. Some are used primarily to access the Internet. Some companies allow you to build your laptop to certain specific requirements. Laptops are available in both PC and Mac formats.
Laptops offer the advantage of being portable, allowing people to work wherever they are. This is a great advantage to business people when they travel. College students also enjoy the flexibility that a laptop provides. Some colleges now require enrolling first-year students to purchase laptops. Some high schools have the same requirement, or provide laptops for their students to use. Other people are working to bring laptops to countries in the developing world. These machines cost $100.00 and are powered by a hand crank, enabling people with little or no access to electricity to word process and access the internet.
