I'm not with Microsoft either.

It's not hard to see who will find this useful, though. Anyone who commutes to work via bus/train/subway will. Taking a laptop out in those environments is just not realistic. There are lots of other situations where you have nothing better to do than sit and wait. Doctor's offices for example. Or maybe you simply feel like going outside to a nearby park yet have something you want to catch up on (Channel9 Videos, for example). You can probably do this with a PDA, but the new Microsoft Media devices give you one more option.

My $0.02 worth.
