I think the RT has a place in the market, but MS priced it way too high to begin with. For $300 with keyboard and allowing installation of non-MS Store apps could make this device useful. It comes with MS Office with OneNote (albeit crippled without the ability to record meeting audio). This could have been a great, affordable tablet for business users and students.
MS didn't include Outlook; didn't include the killer sound recording feature of OneNote - instead recommending running a sound record app while taking notes - WTF?; made it difficult for PuTTY or apps like it to even consider porting to the platform - see http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/winrt.html
Other smaller issues like going with 16:9 instead of 16:10 makes trying to read a document in portrait orientation difficult. MS might have had a tablet for masses and students,but managed to fumble another opportunity by trying to out iPad the iPad.
