I recently got xperia x10 . its damn sexy looking phone. Touch is good ( but not as great as iphone ) but it definitely looks far far better than the iphone. it runs on version 1.6 which while motorola milestone is already far ahead of it. the updation ll be available in Q4 according to SE. Another negative in this mobile is its speaker volume is too dim , you have to press the phone to your ears to hear rfom other side.
Third negative is its battery life. Have to charge it twice in a day . rest it depends upon your usage . But if we wont browse on this type of phone then what’s the fun of shelling this hefty price.
I suggest that you should better wait for the upgradation of software coz in that both speaker and battery life ll be taken care of ( according to SE ) . Rest the phone looks great .
