The XO-1 design has not aged well(and the keyboard was always a disaster); but the screen performed quite well in greyscale(200DPI, sunlight readable). Color cut the resolution and led to weird artifacts(as a cost saving measure, the RGB subpixels were generated by a filter behind the LCD, so the panel itself didn’t have RGB subpixels. At least for the time, it had pretty dense greyscale pixels; but the effective resolution dropped sharply when doing color because the pixels were pressed into service as subpixels.
Panel refresh rate was unexciting, certainly not gamer material; but more or less identical to other LCDs of the period. The hardware did a pretty good job of making it feel slow, though. AMD was cooperative about firmware and pricing; but the Geode was a very, very, slow part.
