My husband has one. It is pretty awesome. I don't personally like Windows 8 but the tablet itself pretty much blows away the iPad, IMO. However, much like Apple, you basically have to be "committed" to the Windows/Microsoft universe in order to fully realize the tablet's abilities. My husband has a Windows phone, uses Xbox Live and used to have a Zune so he is all dialed into the Microsoft cloud already. If you want a tablet to do real work on, this is it, but if you have REAL work to do that might require installing software, you'll need the Surface Pro. Even the RT, though, is more like a laptop than any other tablet on the market right now. The click in keyboard/cover is really neat and makes the tablet very easy to do work on.
I am personally an Android fan and if you choose to go that route, take a look at the new Galaxy Note.
