Sure, the X10 is receiving a great deal of support from the company, but it's not stopping Sony Ericsson from releasing non-Android devices. The company today announced the Aspen, a new addition to the GreenHeart line and a device sporting Windows Mobile 6.5.3. In addition to the full QWERTY keyboard, the Aspen offers a 2.4-inch QVGA display, 3.2-megapixel camera, 3.5mm headphone jack, Wi-Fi, A-GPS, microSD card slot, a 3.5mm headphone jack, and support for Microsoft Exchange ActiveSync and SPB Mobile Shell. The Aspen offers 3G in the 850 MHz band, meaning that it could be used on AT&T in the US.
Though pricing hasn't been announced just yet, the Aspen is expected to land in Q2 of this year.
