Hey I just made a post about this, but then I thought it's probably relevant in this thread too...
We were talking about the Slingbox, and there's a new version of the Sling Player for Windows Mobile. It's more finger friendly, has a widescreen mode, and supports more devices.
Check it out here:

Sorry iPhone users, I know you don't care about watching a game on a Slingbox when you're stuck at work or anything like that, but it's still pretty nice, lol.
