Definately worth it, even just if you catch the odd movie once in a while.
While you're on the subject...
Has anyone here with a Radeon 9500 or 9700 video card tried connecting their computer to a HDTV yet?
They sell the adapters here:

The picture sucks through regular s-video so I was thinking of buying the adapter, but would like to know if it actually works OK first. Supposedly you can get your computer to do 720p or 1080i on a HDTV with the adapter.
