Best inclusion is that SE have finally realised that their sh1tty joysticks (as seen on T68/610/T630/K700/K750/W800(prob some more)) are completely flawed.
The last four phones i've had have been SE and every single one of them have suffered from the lame joystick issues, meaning to get it to work it needs to be pressed a dozen times, banged on a wall, shaken and sworn at.
Finally in this model they've replaced it with something a lot more robust and seemingly less fault prone.
Apart from that in my eyes its a pretty dull addition to a (currently) pretty dull range of phones. Unless SE hurry up everybody is going to be jumping on the more exciting Nokia N series band wagon, myself included. And coming from someone who hasn't owned a Nokia since an 8310 thats unfortunate for them.
