Apple TV

And, for the same post, on a related subject.

I suspect that this will not necessarily be quite as successful as the iPod. The main issue is that it does not support the common formats that are used for movies downloaded off the web - i.e. XVid appears to be missing completely.The iPod is useful because it plays the commonly available audio format, MP3.
However, I believe there will increasingly be a market for a TV media server. People want to be able to watch their stuff on their TV. (I'm currently looking for something that solves the problem and will probably build my own.)
For example, there are products such as the TVisto. This is a portable hard drive that can be connected to a TV to play the content.Portable hard drives are quite popular as people swap what they've downloaded. The addition of the media player and remote makes this really useful.
However, personally speaking, I would probably not want the hassle of copying media onto the drive and then physically moving it to the TV to play.
I want wireless!
You could go something like the Digital Media Gateway which will play things from across the network. However - it has no storage! You can always add a portable hard drive or a hard drive on the network but that's a bit too much effort.
So my current thought is to roll my own with MythTV.
We'll see.
