Good point, and now that I think I about it, I find it rather strange that no touch oriented platform, not even IOS, implements expose-like window switching. What is up with that?
Android is doing something pretty close in ICS. It's a column of apps with window previews, so not totally Expose-like, but a similar idea modified for the limited screen real estate.

Hmmm... Several mobile OSs implemented tile-based task switching, though most of them are dead or dying now. WebOS, PlaybookOS (?), WP7 and Harmattan come to mind.
As for why iOS itself didn't, perhaps it is because Apple believed that the iPhone's screen was too small for app tiles and didn't want to create visual inconsistencies between the iPhone and iPad versions of iOS ?
My Nokia N900 uses expose-like window switching. In fact, I tend to run 4-5 apps simultaneously on my N900, but only one at a time on my iPad.
The iPad just can't handle multiple apps for several reasons, not the least of which is that Steve didn't *want* it to! He succeeded admirably. ;-)

I consider myself an "advanced user" and Metro is more or less what I've always wanted in window management (with some changes).
In my opinion, the idea of arbitrarily positioned and sized, partially overlapping windows is moronic and archaic. This is why I keep experimenting with tiling window managers. But they're all made for guys with beards who like using the command line.
The way window switching is handled on Windows 8 is kind of stupid. You have to go through each app until you get to the one you want. Personally, I think Microsoft should have made swiping from the left bring up a bar (like the one for charms on the right) that has tiles for each running app. This would make window switching less tedious and also make it possible to see notifications without going to the start screen.
However, I really like the way windows can be arranged in Metro. 99% of the time, I have either have one maximized window or a roughly 3:1 vertical split (one main window and one secondary window), which is what Metro offers. My only wish is that you could stack windows in the narrower side as you can with most tiling window managers.
