I have- a PC-DOS 7 laptop with windows 3.1 that I usually fire up at least once a month for one reason or another.
Seems to be having issues now, though.
My other laptop isn't fired up near as often- (although around a year and a half ago I used it almost all the time), it has windows 98SE, 144MB of RAM and a 133Mhz Pentium.
the LCD is the crappy passive matrix kind. works for the most part, hasn't been able to read my burned CDs for the last while, but I believe it's an issue with the brands...
maybe the poll should use checkboxes?
