From ubergizmo:
If you thought the Asus P525 offered good value for money with a quality and performance levels that are a step above its class, you will definitely be blown away by the Asus MyPal A639. It is powered by an Intel XScale 416MHz processor, 64MB RAM and read this - a whooping 1GB of ROM. The MyPal A639 is also a very capable GPS system with its integrated SiRFStar III chipset, and offers WiFi and Bluetooth 2.0 connectivity for seamless networking operations. The only oversight by Asus would be the QVGA TFT LCD that might not be sufficient for hardcore VGA junkies.
