I've noticed, during my search, that the vast majority of LCDs (monitors and LCD TVs that also come up as monitors) don't have glass screens. I think it has to do with the major glare you're going to be getting from those, and how it'd make the monitor more fragile.
Funny you brought up the 971p, since that's also one of the monitors that's running neck and neck with the VP930b. Unfortunately, the novel stand seems to have quite a few problems, there aren't any physical adjustments to speak of (big negative, IMO) and the colors become yellow toward the edges. Other than those common complaints (one is that it's too bright, but the VP also has this "problem") it's damn fine.
But the lack of actual buttons and the constant mention of the packaged software/drivers leaving bits/artifacts on your screen and the difficulty involved in calibrating it really made me wary.
BTW, props for the Cowon mention in your sig. The A2 is fucking fantastic. Does just about everything well, gorgeous screen and a long battery life to boot. The only negatives I'd give it are probably the little jog stick and the lack of a removeable battery.
There's nowhere I can't reach.
