The Google thing certainly looks interesting. Can't quite figure out what gestures are being used yet.
I was thinking on the issue of the convergence of the "touch" OS (iPhone/Touch/iPad) and the "desktop" OS (full OS X). My initial thoughts were that Apple's long term goal would be to concentrate more heavily on the growing the touch version and moulding the way that we use computers to be more task-based like the iPad rather than the all-in-one lump of the desktop. They'd get Adobe to develop a touch rewrite of Photoshop or more likely develop their own competitor and create new innovations for working with images, lots of things like that. Possibly we'd have an "iDesk" in place of an iMac, etc (and there are strong rumours of a touchscreen iMac coming soon so it could be a step in that direction). Basically in Star Trek terms we've got the Padd, and now they'll give us the consoles
It'd be an interesting development if a lot of thought was put into it, and Apple would *love* it as it'd give them an excuse to have everything go through the App Store, giving them full control and some very tidy profits.
But... I think they know as well as we do that vast numbers of people (myself included) would not be pleased if they started down a long term path of making the touch based systems the next major generation of Mac and ditching the "classic" OS X (something that they'd do over the course of a decade or so but which would be quite noticeable and painful to watch!). So my theory has updated a bit - OS XI. A near-complete rewrite of the Mac OS, designed from the ground up to be "input method independent" - great to use either in the traditional mouse+keyboard way or by touch, with an interface that simplifies or complicates depending on whether it's installed on an iPad or a Mac Pro for example. The App Store would be present on all systems of course, but installation of non-appstore software would also be enabled - but only on the Pro range.
Just some idle thoughts really. To be honest I'm probably thinking way ahead here - Apple are known more for incremental updates nowadays than revolutions (iPhone excepted).
Edit: OT sidenote, just got news that the noisy fan(s) in my Macbook Pro have been replaced. It was dropped off less than 2 hours ago. That's MUCH better! I'd say they've redeemed themselves for the 18 day iMac repair for that. The tablet is now penned in to the shopping list
