Tom Walsh has been hard at work building an add on board for the Zipit Wireless Messenger “IM Device for Teens”. The board adds a mini-SD card slot, RS-232 (using a mini-USB connector) and a power supply for an EL backlight. I’m impressed that he got everything to fit inside of the case, very slick. A year ago we covered putting Linux on these devices. Have any of you readers picked up one and what fun tricks can it do? I looked around and they still cost over $90. I should probably just resurrect my Zaurus and be happy
