Collector of vintage "proto laptops" (e.g., TRS-80 Model 100) and handhelds/PDAs. My own preferred handhelds are Newton OS-based but my collection includes Windows CE devices, proprietary devices (early "organizers" with no add-on software possible), DOS handhelds, and PalmOS PDAs...so far.
At this point, I have a MP 120 and an eMate 300 and am on the lookout for an MP2100.
