After a usage around 4 months this is not a good phone to buy though features are good.
Pros:
1.The touch screen is awesome
2.Apps like android market, edge etc are really good
3.3.5mm audio jack best option as I faced many problems with the earlier SE mobs I had.
Cons:
1.No equalizer and music settings should bear with it - one cannot expect and accept this from sony ericcson with the quality of sound they have
2.Sd card cannot be accessed when connected to pc
3.No qwerty type key function on touch though sensitivity is good
4.Battery life is hell, I dont know with what minds they created this mobile.better to be used as a landline hooked up with charger everytime and everywher you go.less than half a day for normal usage and worst when connected to net nad moreover the battery is integrated cannot use a spare battery either.
5.Camera quality not so gr8 for 5MP(samsung galaxy is better except for android)
6.Speaker volume not upto the mark
7.Different kind and idea for charger for cost saving to company.not for customer
With price tag around 16k and from a company like Sony ericcson this is not a mobile one would expect to buy and struggle later.
