The successor to the A636, the new A639 comes with several enhancements. Among them, additional support for 802.11g wireless and Bluetooth V2.0.
Most notable is the upgrade to a 1GB memory (from the 128MB ROM on the A636), making the A639 one of the few Windows Mobile devices sporting the highest onboard storage capacity. Only the Palm LifeDrive offers more built-in memory among handhelds so far.
Design-wise, Asus has apparently stuck to similar dimensions as the elder sibling, with the A639 measuring 122mm by 73.2mm by 19.45mm and weighing 187 grams. A swivel patch GPS antenna supposedly offers better signal reception.
Also onboard are: A 3.5-inch QVGA TFT display, Intel XScale 416MHz processor, 1,300mAh removable/rechargeable Lithium-ion battery, and SD/MMC/SDIO card expansion slot.
