A few years ago I toyed around some with the Sharp Zaurus SL-5500 handheld. It was nice having a palmtop unit that I could use for a host of development and administration tasks with the aid of a wifi card. Now I see these units being advertised as refurbs for only about $150 US so I picked one up again to see if I can use it as a platform for my company's salesforce. Has anyone installed Ruby on the Zaurus?
