Anandtech published The 2015 MacBook
A quote from the article:
I?m still not entirely sure when it actually happened, but at some point over the last couple of years the crossover between tablets and laptops stopped being an idea and became a real thing. Perhaps it was Microsoft's Surface Pro 3, which came out as an x86 Core architecture tablet that was finally thin enough to no longer be an awkward laptop without an attached keyboard. Or maybe it was the more recent release of Intel's Core M family of CPUs, which brought the Core architecture to a sub-5W design for the first time while making the overall SoC thinner than ever before.The 2015 MacBook Review @ Anandtech
But either way you cut it, the line between tablets and laptops is blurrier than ever before. The performance of tablets is continuing to improve though faster CPUs and unexpectedly powerful GPUs, all the while laptops and high-performance x86 tablets are getting thinner, lighter, and lower power. There are still some important differences between the devices, and this is a consequence of both current technological limitations as well as design differences, but clearly the point where traditional tablets end and traditional laptops end is no longer a well-defined one.
This brings us to today's review and today's launch of Apple's latest ultra-thin laptop, the simply named MacBook. Though Apple's device is distinctly a laptop in terms of form factor and design, you?d none the less be excused for mistaking it for a large form factor tablet if you took a look at its overall size and internal configuration, both of which are far closer to a tablet than a laptop. Apple may not be doing any kind of wild 2-in-1 transforming design, or even pushing the concept of a touchscreen OS X device, but they have clearly tapped their immense experience with tablets in putting together the new MacBook.
