Samsung and AT&T have launched the SGH-i907 smartphone, dubbed the Epix, that's a sort of sucessor to Samsung's Blackjack range.

Samsung's first AT&T Windows Mobile 6.1 Professional device with touchscreen capability, it's aimed at enterprise and small business customers.

The Epix has a world first claim as it contains an optical mouse, or as AT&T phrase it, an: "optical center navigation button with mouse pointer enables easy one-hand operation for even the most complex multitasking needs".

Otherwise the device is a fairly standard 3G smartphone with a full QWERTY keyboard and business-friendly features for IT departments.
