Also agree that it's just going to get more powerful and versatile without the need of putting a major full on desktop OS on the unit.
The point I was making about MS was they keep thinking is that all people want is a keyboard. They believe they majority of people just want to go back to laptops. But it's not true. MS just want to bet everyone back to the OS is king scenario and the OS should be windows.
You're right to an extent. MS has the framework built for an appcentric OS with RT. In fact, I could say that in some ways it's better than iOS. They could break away if they really wanted to, but...
...they haven't. See, MS doesn't have the luxury of being able to start over from scratch and build an entirely new environment like Apple did with the iPad. There's bit of an expectation for all MS products to be backwards compatible with each other. Windows is so ingrained, they can't just pull the trigger and say here you go, something entirely new and awesome, without pissing off whole loads of people.
I think MS realizes they need to do a clean break to get the most out of their mobile new platform. Thing is, they're not willing to commit to it 100% like Apple did, and so we've ended up with this bad hodgepodge we're seeing now.
I like a lot of the things MS is doing, but the implementation leaves much to be desired. And as long as they waffle on the issue, they're going to lose more and more marketshare to Apple, Google, and maybe even Linux.
