I'm a repair guy at heart. Cut my teeth in a Mac repair shop. They are virtually unserviceable and completely non upgradeable.

Not to mention, very pricy.

I'd love to have one but I'd never buy one. And the SSD drives are nice and fast but very unreliable. Defiantly need to use time machine.

I don't object to their existence but I REALLY hope they don't replace the workhorse line of MacBook Pro's they've taken their name from.
