I think if someone's running a majority of metro apps it might be a bit less jarring (because they are used to the "app as the whole screen" thing), but it can be confusing when switching, and the switch feels a bit like everything else has "closed" if you're used to the task bar. The windows key acts as a good anchor though, everything feels pretty close at hand.

I do like that quick little context box for the other installed apps. Advantage to how that app selection context box works is that it scales with the users expertise - if you do see it, it means you've installed software, which probably means you understand why the selection is necessary. Average mum and dad user probably won't come across it / get confused by it.
