Apple MacBook (2015) review


Gawk, but leave your wallet in your pocket: Apple's new MacBook is an engineering marvel and a terrible value.

12-inch MacBook review


(Shot on location at WeWork. Also available on YouTube) Apple's latest laptop is simply called the MacBook. Actually, I suppose, you're going to see everybody refer to it as "the new...

Incredibly thin ; Beautiful Retina display ; Great keyboard

Processor-intensive tasks are slow ; Laptop gets warm ; Only one port for everything

Review: Apple MacBook


Apple's newest laptop may not make a lot of sense to you at first glance, but it clearly represents the future of computers.

This is about as well as you can design a clamshell PC: I still don't understand how a laptop can be this light. The screen will make every Air owner jealous. If only all laptop chargers were this small

Expensive to the point of being hard to recommend. A little slow when you push it. The battery is just shy of being as worry-free as it wants to be. USB-C isn't yet everywhere

Apple MacBook 2015


The complaints started even before Apple's first new MacBook demo ended. During the March, 2015 press event, observers fretted about the new, slimmer, lighter 12-inch MacBook . "It's underpowered," they said. "The battery life will be short. The new...

The new 12-inch Apple MacBook is amazingly thin and light, has a premium look and feel, and is available in three colors. It offers better battery life than other laptops with Intel's Core M processors, and performance that's as good as or better than...

Its performance and battery life falls short of the MacBook Air and Pro. The new keyboard is shallow and takes some getting used to, and sharing a single port for all accessories as well as the power cord is almost immediately frustrating.

If you can live with its limitations, the new 12-inch MacBook delivers a groundbreaking design that points the way to the next chapter in laptops.

Review: The new 12-inch MacBook is a laptop without an ecosystem


If you value portability over power, and you don't need to physically connect to much, the new MacBook might be for you.

Thin and light, with great battery life ; Beautiful Retina display ; Force Touch trackpad

Weak keyboard ; Single USB-C port for charging and peripherals ; Slow Core M processor

The new MacBook is the future of Apple laptops. The Force Touch trackpad, Retina display, and 2 pound weight make up for the MacBook's weak keyboard and slower performance, but not everyone can live on...

Apple MacBook 12-inch Retina (2015)


Remember when folks flipped out over the first iPad's lack of a USB port? Like that game-changing tablet, Apple's new MacBook is defined just as much by what it leaves behind as what it packs in. To create one of the thinnest and lightest laptops ever,...

Apple MacBook 12-inch Retina (2015) Review


Wonderfully light yet sturdy aluminum design; Three color options; Keyboard remarkably fast; Awesome stereo speakers; Strong battery life

Must use dongle to plug in most devices; Pricey

The new MacBook is a fantastically light and compact laptop that delivers a rich display, long battery life and surprisingly strong ergonomics, but it needs more ports.

Apple MacBook 12 (Early 2015) 1.1 GHz Review


The art of omission. Sometimes less is more, which is what Apple probably thought when they designed the ultramobile MacBook 12. Besides unnecessary weight, they also removed (almost) all the ports. A radical concept that won't suit everybody – and...

careful build quality and very high stability, extremely low weight as well as compact dimensions, excellent touchpad, bright Retina display with wide viewing angles, good everyday performance, decent battery runtimes, fanless, powerful speakers

only one combined USB and power connector, bad webcam, no maintainability or upgradeability, high price and expensive accessories, only 12 months warranty

We could start to criticize the poor port variety, the lack of expandability or the low 3D performance – certainly points of criticism that are worth noting. You do, however, have to consider the target group for the MacBook and whether these issues...

Apple MacBook (2015) review: Thin and beautiful, but worth the price?


Haven't we been here before? Following the new MacBook's announcement last month, I was immediately taken back to the year 2008, when Apple introduced the first MacBook Air. It was so thin you could stuff it in a manila envelope; it was a neat party...

If the sacrifice of performance is worth the thinner, more modern form factor, than by all means, go ahead and spend the $1,299 on the base model. If you value performance, however, then the new MacBook isn’t for you. This is a first-generation device...

12-inch MacBook (2015) review: Lighter than Air, but at a cost


After more than four years of identical-looking MacBook Airs, Apple finally made a next-generation MacBook that ticks all those boxes we've been asking for. The "new MacBook" is lighter and thinner than the Air, but also has a Retina Display like its...

, which is to say it's lighter than any full-blown computer has any right to be.
