I think that's a pretty good analogy, and I rented a Hyundai last week and thought it was pretty OK.
What I find interesting is when someone will desire a high end display to the point of immense stress over which one (we all are doing that, right?) and then cheap out on the source.
I'm a picture quality snob, I admit it, but why worry about every little nit on the display and then watch Wheel of Fortune in SD or DVDs on some old crap player? I'm at the point where I find a lot of HD, even OTA, sub par. If you watch a few HD DVD or Blu Ray discs this might happen to you as well.
It's one of those points in the leapfrog race where the displays are often more competent than the source. In the computer world this happens now and then, but usually the hardware is lagging the software. We're kind of at the other point right now with video. Aside from HD DVD and BluRay the displays are outpacing the capabilities of the source material.
