Hopefully you can completely remove it. Bloatware is rather annoying. I just dislike that they're bringing it to PC's. Rather it stay with tablets and phones.
This video is actually pretty old. This is windows for tablets. The whole point of W8 is that you have full functionality of windows in a tablet PC. You CAN switch back to the traditional desktop layout with added features of W8 for tablets. W8 will also let you play 360 and upcoming microsoft console games as long as you get a special drive for it. I'm looking forward to W8
