The idea of a media PC appeals to me - or even better, a media server (capable of storing DVD's and uncompressed CD's) that can be accessed from networked clients around the house. I think that even with the plummetting cost of hard drives we're not quite there yet for storing complete movie libraries (whether it's a HTPC or a server somewhere else in the house), and the thin clients are still evolving for the server concept if you want to include video in the mix. It's still not quite time to start removing inputs from processors, at least component video, digital audio, or DVI/HDMI - people are going to continue to have cable or satellite, DVD, HD-DVD/Blu-ray, game consoles, and other stuff to hook up.
