This product represents an insult to every consumer in Apple's market area. By trundling out a "computer" that's so hopelessly crippled like this, Apple is testing the stupidity of the marketplace. The question is whether you'll call their bluff, or vote for a huge step backward with your money.
Actually, this isn't even a step backward, because never(as far as I can remember) has there been a computer so hampered by egregious design decisions.
The primary flaw with the MacBook, of course, is its near-total lack of ports. This thing has one port, and it's tired old USB. This decision is simply baffling, since Apple has championed the far more versatile and modern Thunderbolt standard. If you're going to put only one port on a machine, why wouldn't it be the one that can carry USB, video, raw data, and network traffic all at once? And be daisy-chained, so numerous devices can be connected to your one port? That's THUNDERBOLT. And it's inexcusably missing from the MacBook.
Pros:
Sleek ultraportable 12-inch laptop weighing just 920g
Impressive Retina Display
Improved battery life and GPU performance
Cons:Expensive
Few upgrade or repair options
Limited connectivity
