The IBM WorkPad Z50 (cache) is a small Windows CE subnotebook that was obviously thought as a compantion to the lager IBM notebooks (ThinkPad) at the time. As far as I know, it was sold in the USA and Japan only, around 2000/2001. Got mine from eBay.
The Z50 was quite popular amongst hackers because of it's PCMCIA slot (for wireless cards) and it's massive battery lifetime (about 8-10 hours with the extended battery).
The system is based around a NEC vr4121 (cache), whose 133MHz CPU core is MIPS r4000 compatible (minus the floating point unit).
There used to be a Linux port (cache) to the vr4xxx series, which I remember having booted once. It seemed a bit flakey to me, so I switched to NetBSD/hpcmips (cache), which runs quite fine on the system (including X) with only a few minor quirks, like when suspending while X is active.
The following picture is the Z50 with the normal WinCE environment (quite distorted by my camera, usually the case is square):
...and while booting NetBSD:
There's also a dmesg created after netbooting my rescue system (I'm currently trying to make NetBSD 2.0 run on the Z50, but keep bouncing into kernel crashes):
