Well, I bit the bullet and bought it anyway.
Fullscreen DOS games don't look that bad, even when stretched to fit the 16:10 screen.
I had some hassles initially getting the thing to work in 1440x900, but that was easily resolved by cutting & pasting the "Screen," "Monitor" and "Modes" sections from
this person's xorg.conf file. Hooray for open source.
This monitor seems to support sub-pixel rendering better than the old BenQ did. Text is visibly sharper. I'm happy with it.
The only disappointment I have is that apparently there are no 1440x900 vesa framebuffer modes. Occassionally, I like (or need) to start up in text mode, so I'll have to put up with a stretched 1024x768. But, other than that, it's all good.
