Re: Windows RT
You're assuming people will use this. And if they do, then you're assuming the interface will be coherent. And if it is, then you're assuming that it won't be so buggy that it makes people stop using it. And if it isn't, then you're assuming Microsoft would allow you to do anything with it. And if they do, it's just another Microsoft device you make fun of people for using.
Microsoft might have a few hurdles to overcome in a race they've joined years late. But to answer your question, wait... Windows R what? Anyone remember?
