I have a powerbook 190cs which is actually my main 68k machine. I have a good ethernet pcmcia card so I can connect it to my network and copy files there. I also use it as a localtalk bridge between my wifi network and my old localtalk network (mainly used by pluses, classics, SEs) It's running system 7.5.3 so it's quite speedy (can run up to 8.1). My battery even works perfectly fine (replaced by prefvious owner about year or so ago) and it holds about 2h+ of charge. The screen is acceptable, it's not so bad (unless you play lots of games). The worse part I would say is the keyboard.
