I had a Surface RT for couple of weeks before returning it. In the end it didn't fit my needs, but I certainly liked a lot about it. Well, I got a chance to play with the Pro at the store last evening, and had to come back here to give my 2 cents... I have to say, I don't get it at all. Yes, it's snappy, and yes it has higher res screen, but it runs hot, it has a fan that you can actually hear, it's much heavier and thicker, and from all accounts, the battery life is close to 3.5 hours... What is the point?? It felt like I was back 10 years ago or so, trying to desperately find a tablet. At the time I bought Samsung Q1U, running Vista... Made about as much sense then as Pro does now - crappy tablet experience, and a compromised laptop experience, all for way too much money. The difference is that back then there were few other options, unlike now.
I really hope that MS sticks with Win RT and develops it further, and that the next Surface RT addresses most of its known issues. It makes much more sense as a tablet, and has the potential to become the 3rd player.
