To answer your second question first, Matrox hasn't given up on WinNT support. Much of their focus lately as far as drivers is getting a "final" OpenGL ICD. This being done (although they'll probably update it), they'll probably rework the WinNT drivers.
As to who uses Matrox, the first group would be those that need the best image quality - graphics, CAD (Kruzin?). The G200 series wasn't the greatest card for gaming, but the image quality couldn't be touched.
The G400 series does well both on the graphics/CAD end and for games. Again, it may not be as fast in some benchmarks as a TNT2/TNT2 Ultra, but it's no slouch. I'm definitely not disappointed.
From what I understand, there currently isn't support for OpenGL under WinNT, at least for the G200. I believe the G400 does have OpenGL under WinNT. Since your using your 'puter for both real work and games, the G200 or G400 might be a good match.
