I agree. I think somewhere in between is a good balance (I have a 50"). The distance at which you are viewing the TV is also a big issue, especially with HDTV's. There no hard and fast "rule" but with a 50" screen, you should be at least 8-10 feet away.
I have also seen TV (both regular and HD actually) on a a projection in a relatively small room and I found it awful.
Actually there is a rule, primarily from the
SMTPE; for a 4x3 aspected TV (the Standard Definition square shape we've all grown up with) the recommended distance is 2x the screen's measurement in inches. So for a 36" TV, they recommend sitting 72" or roughly 6 feet away. For a 16:9 aspected TV (widescreen), they recommend 1.5x the screen size, because of the field of view...so a 43" TV would be roughly 5.5-6 feet. Those, however, are the minimum viewing distances.
All of which, however, is just a guideline, since part of the experience is subjective. However, many large TVs need to be viewed from a distance, or you get distracted by identifying the individual picture elements. When watching an SD picture on an HD tv, if the TV doesn't do a good job of converting the image, you'll notice lots of 'jaggies' and other artifacts. It's not that the picture has changed, just that it's become big enough that you can discern the elements, which becomes bothersome.
As for TV viewing in the store...it depends on the store. If you go to a Circuit City....well, just don't.

Best Buy isn't as bad, but they still don't have the ability to truly show off the TVs or to configure them properly. If you want to look at a HDTV, go to a smaller shop that specializes in such things, such as
Tweeter or
WorldWide Stereo. No one said you have to buy it there...just check it out. I ended up changing my TV choice based on seeing it in the showroom.
Sorry for blabbing on and on, but I spent two years picking out my TV and system, and the opportunity to actually use all that research makes me chatty.

All the compliments I got on Superbowl Sunday was very validating.
