If the one device happens to be a PC, then it's quite possible that the pre-pro is not severly underutilized.
In any case, to use an example of one device is just silly and transparent. The point is to have multiple devices with one cable each into the pre-pro, and then one cable from the pre-pro into the TV. If we followed your logic, we'd have two cables from every device - one into the pre-pro, one into the TV, and would quickly run out of TV inputs. (In fact, back in the old days, that's what we used to do - but we bought HDMI pre-pros to stop doing this!)
I think you're being overly critical of the choice that someone else is making. The PC is a special case as it's (in nearly all cases) the only source one might have that is capable of generating a resolution other than the standard 480i/480p/720p/1080i/1080p choices. So ALL devices expect the HTPC can have a single cable going to the pre-pro, the HTPC can send audio to the pre-pro, and then the PC and pre-pro can each send HDMI video to the PC. So in the end, it's 1 extra cable in order to optimally make use of the HTPC's video capabilities. RichB is correct that the ATI cards have very high quality scaling, and it's definitely wrong to assume that all current TV's will do a better job than the PC will at this. Further, for the PC desktop you would most definitely want to use the native resolution of the display so no scaling is done at all to get the very best picture quality.
So it sounds like your the one guy who would happily buy a BluRay player (and HD Game System and HD DVR) with two HDMI outputs on it - one for video and one for audio? Nifty. I'm sure someone will be making those soon.
Now who's being silly? Come on, that's not what RichB is suggesting and you know it.
I would be surprised if the ATI does a better job of scaling than your TV, but perhaps you just have a really old TV or something?
Unless the TV is a Pioneer Kuro, I wouldn't be surprised at all.
Bottom line - If you find yourself using/wanting/needing two HDMI cables for any single source device, then something is wrong or very old in your setup. In your specific case, it's probably your TV.
When the device is a PC, I strongly disagree.
