A used IBM Thinkpad, model 760XL laptop (P166, 104 meg RAM)
running Red Hat 7.1/7.3. Sure, it's slow and has a funky
keyboard, but it beats the heck out of a No. 2 pencil and a
Big Chief tablet.
Update: upgraded to a
770Z Thinkpad (P2-366, 192 meg RAM) running FC3. Anyone
feel like donating a later-model laptop to a starving writer
