All I take from the article is that Windows 8 is different, but at least it is backwards compatible. New programs/aps will need to be made that integrate better into the new environment.
The thing I wonder, will I be able to have multiple windows visible on my screen at the same time, or will I be limited to everything full screen. I like to have a video on one side of my screen and my work on the other side... Will this still work???
