PlayOn. Coming soon to the Wii, but you need Windows?
I just learned about PlayOn, which allows you to watch Netflix and Hulu content on various game consoles, with support for the Wii coming in early 2009.
This all sounded good, but it seems that it relies on a Windows PC to stream the crap to the game console, it doesn't allow the game console to do it all itself. As I don't have a Windows PC in the house (at least not one that's always running Windows, Sarah can reboot her Mac into Windows if the need arises) this is of little use to me. No sale.
