I also decided to try the Palm route with Cachemate and GSAK. My wife saw me "bottom feeding" on ebay for one and the next day brought three of them home from her office. They haven't used these models in years and the I/T person had them kicking around and was going to throw them out. I got a Palm Vx, a IBM Workpad C3 and a IBM Workpad 30x. The Vx and C3 seem to us ethe same cradle. Does anyone know what these IBM models are equivalent to?
