Until now sony phones were slightly better in camera feature but with the release of n73 i guess nokia has finally produced a sony slasher . It's camera is so better then over hyped k800i . I have not seen n73 personally yet. But i have seen k790i and it was pretty disappointing .
The lens conver was rather loose,the thickness was uneven and the joystick was even poorer then k750i .
Also i think that sony phones are for amateurs . That is people who want good features but do not want to work hard to get it .
For example, try watching a movie more then 1 hour in length on any sony phone . It refuses to play. However on symbian phones it is a bit of cake with smartmovie.
The same case applies for internet ,contacts , and with the release of 3rd edition symbian nokia probably has even a faster ui.
I will make it clear here that i am not a sony hater. It is just that their new phones like k790 and w850 are not on the same level as k750 and w800 were.
