Yes, but his friend who recommended it to him gave it stellar reviews. His main complaints were, he was used to the mac keyboard/shortcuts, he was used to the wacom quick keys, at times it would lag, and he had trouble seeing things on the screen. The only complaint that wasn’t the user, was the lagging. I’ll agree it isn’t for everyone, but even my Motion Computing windows tablet which is over 8 years old, runs photoshop fine, and it doesn’t have nearly the chops of the Surface Pro 2.
I also use my iPad for totally different purposes, and yes I too have large apple monitors and a wacom at my desk. When traveling, away from my desk, on the road, etc. those large monitors and wacom don’t do me any good, and like you said you can’t do the same things on the iPad, that is when having a wacom enabled tablet pc really out shines a mac book air. During the summer I sometimes like to sit out on the deck in the sun and use it. It is no franken computer, far from it. It is a great device and well worth it for anyone who isn’t a deskbound type of person. If you are deskbound then it probably isn’t for you, if you aren’t then it sure beats the crap out of a mac book air. If only apple would step up their game and make one, then i’d be a happy person.
