I mean this thing is like MAJOR. I'm still thinking about it. The first modern tablet with a Desktop OS on it (referring to RT). If it's priced decent, do you know what that means? Let me run down the scenario
Apple: Let's say I never bought an iPad but wanted a tablet. Something that does more than just run the same apps on a bigger screen. What if I'm at work and I have free time to jail break my phone but don't want to lug around my laptop? BOOM, this'll work
Blackberry: Never really cared for the Playbook and biding my time until more apps become available. Don't want a Kindle or Nook tablet and not interested in Android. Windows RT has USB ports, which means I can sideload media until my phone. I have a WORKING desktop OS on the go
Android: I want to reflash my phone but I'm not at home with my computer. THIS. WORKS.
So yes, I see A LOT of fear from the people who have committed their lives to a vendor for whatever reason. This appeals to EVERY OS user out there. You can load iTunes and Zune on this, side load files to your device, AND not have to be inconvenienced by carrying a huge device. I see a lot of things in my house that can be replaced by this
