Tom....as long as you have a wireless router, you can use the Airport Express. Works great with my old Linksys wireless router.

The Airport Express does not use the TV's screen. There is a third party wireless remote available, but I do not know how well it works.

I don't find myself going to the PC often to change songs. I just set it to a playlist and let it go.

I have also looked at the Prismiq, and think it is a great alternative. I almost went that route...and still might down the road.
