I honestly don't find it that unintuitive. I may have a leg up since my primary pointing device is a trackpoint, which makes hitting the screen corners a really easy move. When you hit the corner, there are visual hints that pop up to guide you to the start screen, sidebar thing, or open applications list. there are definitely some things I would have suggested that they do to help people into the new interface, like a guided help or pop-up tips, but a quick google and 30 seconds of reading were really all that was required to get into it.
