I'm pretty sure I saw a Viewsonic 17" 16:10 LCD at an electronics superstore recently. It was actually quite nice. Very good contrast, and viewing angles, I think the pixel picth was ~.27. It ran around $800-900 though. I'll try to track down the model. Can't remember if it had DVI.
I'm test-driving the Samsung 172W 17" 16:10 LCD. While it's ergonomics are beautiful, I've got a few nits to pick with the picture quality as well, mainly with the "blacks", and weak viewing angles. So I'm looking for something else.
FWIW, I thought a widescreen would be ideal for me, since my applications principally involve widescreen video. But after using it for a few weeks, I'm finding that I miss some of the extra headroom/resolution of a 4:3. The vertical resolution of the 172W is only 768, and pixel pitch is ~.29. So the experience is a bit more akin to a 15" 4:3, in some ways.
