Re: Probably not so much the form factor
I have never understood this apps criticism. I have a Surface 2 (and had a Surface RT before that) and in all my time with Windows RT, I've installed probably half a dozen apps on those devices (an SSH client, a code editor being the main things). It does nearly everything I need already - it comes with Office, email clients, full featured web browser.
Apps evolved because mobile devices didn't have screen real-estate or properly functional browsers. Windows RT has that. Unless you have a burning need to play the latest games (I'm not a gamer) then I genuinely don't see any serious lack.
