The XDA mini is about two-third that of the XDA II. The mini is so only for the namesake, for the XDA mini even beats the XDA IIs with its faster 416 Mhz processor. A 1.3 Megapixel camera and a 256 Mb SD card included with the package soothe the dissapointment that one may feel with the 64 Mb RAM and equivalent amount of ROM which is lesser then its larger version. No Wi-fi and a smaller display which is the obvious result of size reduction are the only negative points that come to mind; in all other respects the XDA mini is a stunner. Perfect for those who want a PDA with small size yet all features.
