I'm still a bit sceptical of this. Metro only allows you to work with one app on the screen at a time and you have to hit start every time you want to switch apps instead of a taskbar.
If people want to use their desktop computers in such a way, why didn't they build the UI this way years ago?
I've long since opened and closed things since last comment, but I've got lets see.. 5 windows visible on my screen right now. This browser, a XenCenter session, an IRC client, a script for that IRC client, and a miniaturized iTunes.
2 is such an absurdly low limit as to be virtually useless.
