PC-Z1 NetWalker "smartbook" is a total tragedy or total triumph of technology. On one hand, it's running a full Ubuntu install at a relatively high resolution and a rather snappy pace. On the other hand it's nearly impossible to use, with a too small optical track pad and a too high pixel density -- combined they make hunting down just about everything in the OS a painful affair. The QWERTY keys are also astonishingly bad for their size, spongy and brittle all at the same time... but, somehow, we're still fond of this device. Perhaps it's just that unrequited Zaurus love rearing its long-repressed head. Video is after the break.
