Engadget says the HTC Athena (X7500) is not a UMPC but a Windows Mobile PocketPC with a 3.5-inch touchscreen and a detachable QWERTY keyboard.
The unofficial specs being passed around indicate that this handheld is destined for Europe: UMTS 2100 with tri-band GSM/GPRS radio (what, no EDGE or HSDPA?), 802.11b/g WiFi, 256MB ROM / 64MB RAM, 2 megapixel camera, SD expansion, and USB 1.1 interface. All running on a 400MHz Samsung processor.
