Just came from the Microsoft Store in Times Square (yep, I was there at Midnight) and came back with two opinions.
1) The Surface hardware is REALLY nice in person - the tablet is really sensitive, tight and a pleasure to use. The screen looks absolutely amazing, despite the 1366x768 resolution. The keyboard was slightly annoying to use, but after about 2 minutes, I got the hang of it.
2) The tablet has absolutely no value in regards to apps. We sat there for about 20 minutes and were thoroughly done with the hardware - there was nothing else to do. We tried 1080P YouTube clips (choppy) but it handled 720P fine. Apps were allowed to be downloaded for free, and even then, there was nothing to really use.
Also, the staff in the Times Square store is absolutely god-awful. I have NEVER seen a bunch of people so mis-informed about the hardware they are selling, or the way computers work in general. For example, I downloaded an MKV file to see if it would play, and I was told ALL downloads are blocked unless it's Microsoft approved. The person had no idea between downloading files vs downloading apps. Needless to say, the MKV did not play; instead I was pointed to some app that can check filetypes or something. I honestly don't know what the app did.
Trying to explain to them that you'd rather an Intel Atom of Core-based laptop was also met with furious explanations about how tablet and phone apps are the future, and that their market was already a leader, with XBOX integration.
Ugh. I'll never consider an RT. Seriously, play with one for 20 minutes, and every impulse you had to buy it will disappear.
