That looks pretty cool. I wonder how easy its going to be for people to discover the gestures because they seem to be so different than Android/ios. That swipe from the edge is going to be a hard one to learn/commit to muscle memory.

it looked like that kid wasnt really doing that stuff on his screen.

They look a lot more intuitive/natural than iOS. I actually had to use Google when I first got my iPad to figure out how to do some pretty basic things. In fact, I didn't even think to look into it until I accidentally put my whole hand on the screen and unexpected things happened -- it made me question what else was there.

Why is "swipe from edge" hard to learn? This is one of my favorite things about Windows 8, because in hindsight it's so obvious.

I doubt that the average android/ios user even attempt that gesture. Is what Im saying.

I feel that doing all of the touch gestures with a mouse is a bit much, especially pull down from top to close.

I still havent seen a better solution to multitasking/app management than webos.

Discoverability is a much different issue than learnability. I don't know how discoverable edge swiping is, but it seems really easy to learn.

I doubt that discoverability is going to be a major issue, though, because edge swiping will get a lot of exposure through ads, and through any in-store use as well. It's such core functionality that every Windows 8 touch user will have to learn it in the first 2 minutes. If nothing else, they'll turn to the person next to them and say "how do I get back to the start screen"?

As for closing metro apps, there's not really any need in general. Just go back to the start screen. You can also close apps in the app switcher on the left, but the current app isn't in there if I recall correctly, and it's still not necessary in general.
