My fascination with the Apple Tablet is less around Apple and more around the convergence of several devices which either currently or will play a key role in my day-to-day habits: web, video, applications, etc. Furthermore, it represents the convergence of devices of all formats and sizes: the computer, mobile phone, Kindle, and netbook.
But Gizmodo has a video and several screenshots of Microsoft's "Courier" - a late-stage prototype that reimagines the way a 'tablet' looks and behaves. Its both netbook and Nintendo DS - and as much Amazon Kindle as it is the iPod Touch... all overlayed with Microsoft's touch interface.
Conceptually, I love it. I love it as much for it's innovativeness and multi-touch system as I do for pressuring Apple to release and rethink the Tablet.
