Sharp has been making quite a few nice little Linux-based PDAs while fighting the good fight against the great Palm/MS juggernaut. Unfortunately, a lot of these Zaurii aren’t very accessible here in the States, so buy yourself a ticket and head on over to Tokyo.
Looking like an old-time Sony Clie, the Zaurus only lacks Wi-Fi or Bluetooth to make it just about the perfect wee PDA.
