For example the Sony Ericsson TXT is the first phone from Sony that has a classic QWERTY keyboard. This SE TXT is for people who like to navigate on the Internet, who uses messenger applications on a regular basics, and for those who need to write a lot of text. TXT is coming with a 2.6 inch display, 100 MB internal memory, 3.15 MP camera and a proprietary operating system.. so this is NOT a smart-phone.
Because of his design, I like to say that SE Xperia Active is a “sport” smart-phone. The case is well built, resisting to shocks, water, dust. Xperia Active is equipped with a 3 inch display, 320 internal memory, 5MP camera, 1GHz processor, HD video recording a secondary camera and the Android Gingerbread operating system.
SE Xperia Ray is the most powerful from these three and has a design similar to the Xperia Mini. It is equiped with a 3.3 inch display, 300 MB internal memory, 8 MP camera, HD recording, secondary camera, Android v2.3 Gingerbread, Scorpion 1GHz processor.
