Oh we all know you just wanted to post the firefox girl again.
On topic though, that's pretty cool. Don't use it on a cellphone myself though. However, to all the people who talk about the taskbar as opposed to tabs, personally, I don't like having applications 'grouped' (when I wasn't using Windows 7 anyway, now it's moot), and I have up to 30 tabs at a time often, so it wouldn't work for me. They really do serve different functions, tabs vs windows. Not saying that liking windows for the point of windows isn't a bad thing, but saying that the taskbar is a 'replacement' doesn't really seem valid.
