These tours don't give me a good sense of how the OS works, much less how it will be used by a real human (vs a tech reporter). I guess that's the weakness of shaky-cam recording of a 5 min first experience. That said, some glimpses suggest a very interesting and powerful take on the tablet experience. So far, Android has felt like a bad copy of iOS to me. Android phones, even brand new hardware, are noticeably less responsive than an iPhone, and feel off in comparison. In contrast to the Pre and WP7, it's been basically a lagging derivative of the iPhone (give or take some niceties like multitasking and notifications). But these little previews of A3 suggest some original thinking, a new take on the touch interface and how to manage a 10" screen. It's not merely an endless expanse of app icons. It suggests a set of live screens, each of which is used for some different task, or set of tasks. Perhaps a combination of mini-apps running to give live info, without hopping from full-screen app to full-screen app. It looks like it might be very powerful. It looks like Apple might have some real competition now for a great tablet experience. I'm still buying the first iPad this Spring, for my wife. But I'm interested in seeing a 10" Android tablet before buying my iPad this summer.
