Very detailed review on the new Zaurus SL-5600.
“The new Zaurus SL-5600 from Sharp is a linux-based PDA with a 400MHz Intel XScale (PXA250) CPU. The street price is currently around $500 for the SL-5600. Sharp calls these devices Personal Mobile Tools, and if it were up to me I’d call the Zaurus, say, an “Ultra-Light Computer”, but I’ll use the term PDA here. The 5600 is an upgraded version of the 5500 which has been widely available for over a year, and the appearance is almost identical including the distinctive miniature keyboard which hides behind the quick button panel. The Zaurus is a very feature-rich device with plenty of power and expandability.”
