As far as those limitations go.

1) That would also be true if you are switching to nearly any GUI based app that you need the mouse except for maybe if you are switching to a text editor but I doubt every time you switch apps you are immediately typing something, so not really sure I see the problem there.

2) True, maybe I just don't tend to have a ton of windows open at the same time.

3) I can't really speak on how it behaves with alt-tab however with the track pad it is as fast as you swipe and tied to that swipe. I can slow it down or speed it up.
