Windows Mobile 7 is expected to bring the largest revamp since Windows Mobile 5 was released nearly five years ago. Details of the build are tightly wrapped, but there's talk of integrating Zune, Xbox Live, Facebook, Twitter, and Mediaroom IPTV elements, as well as native multitouch.
Some believe Windows Mobile 7 devices will have to feature a minimum 600MHz ARM v6+ processor, 128MB RAM, 512MB ROM, 3G, GPS, and Wi-Fi. Others say it enforces a 1GHz CPU and 800x480 touchscreen. I supposed we'll find out on February 15.
