I'm considering buying a PDA and I think that I want linux-powered one. The device must cost no more than 350$ in USA. About 300MHz would be OK... It must have linux as OS. Multilanguage support, char-encoding/keyboard layout configuration are must-have features. I want to be able to use gcc compiler on this PDA. Also Grace or OO-Calc is needed. Also I want it to support external keyboard (PS/2).
