I just bought an Xperia X 10 and was happy with its host of features and android software, Its GPS related software are very nice and convenient to use, especially ’wise pilot" however, they could have added a few extra features like:-
(a) Stylus (As qwerty key pad with touch screen is slightly cumbersome to use and you need to get used to it.
(b) Camera Flash (its 8 MP camera could have been better with flash)
(c) FM radio
(d) Something like Itunes for music library. (The music library is jumbled up)
This is not asking for too much if you are spending 31, 000/- for a phone. Otherwise a good phone and I m very happy with it.
