Number one on my wish list is that I want someone to start selling PCI CableCARDs.  For those who don't know what CableCARD is, it's a card that you can get from your cable company that slides into various 'digital-cable-ready' devices, and eliminates the need for a separate cable box.  Some TVs have this built in.  There are supposed to be some personal video recorders coming out with it soon.  But for me, I want to have an HTPC, which means that my computer needs to be able to work with this technology.  That's where the PCI part comes in.  Currently, no one is making this.  If they do, I will buy one.

UPDATE:  So I was thinking about this some more, and I realized that since the cable companies are the ones that have to supply the CableCARD, they aren't likely to supply one in PCI form.  So, what I really need is a PCI card that accepts a CableCARD provided by the cable company AND has a coax input that together will allow the computer to capture cable HD.
