I've got one, older but not vintage. It's a Thinkpad 365XD running Windows 95. Funny coincidence, haven't seen it in years but booted it up this afternoon and it still runs like new.
Bought it about ten years ago, as I recall, from a co-worker for fifty bucks. Used it in motels for a few years - our ISP had local numbers for all over the state - and then put it away. Used it mostly for internet browsing, downloading geocache coordinates and running the Garmin GPS software, interacting with a TI calculator, and playing a few games.
I have some interesting, but probably not rare, accessories for it too. Port replicator, docking station, and a dial-up PCMCIA modem.
