I have actually been pondering this exact question, with the same considerations. I use my work laptop for everything right now, and I don't like that. I don't play games on it, and that holds me back from site stuff, because we've got some Steam games I'd be interested in playing... but not on my work laptop.
I have a friend who's a storyboard artist, and he uses a Surface Pro 2. He has had pretty good luck with it, and in his particular line of work, he's heard some folks say they don't like the 3 as much as 2. But that's all I know. I'd love to get info from folks as well.
