E61i resolution is a draw back. Almost 90% of the games i dl have 240X320 resolution.... E61i have 320x240... So, take note that its also not that 3rd party friendly... Though some s60 3ed softwares run perfectly, like smartmovie and mobitubia, alot of games for s60 3ed are made with 240X320. But i would still recommend this phone rather that the samsung i600 or the 780. Coz the 780 also have issues with 3rd party with its screen resolutioin. Even though i780 boast a better procesor speed, what would you do with it if you keep on running out of batt. The e61i has a more balanced spec as against to speed and battery life.
btw: the samsung i780 comes with one extra batt free. Instead of thinking that it adds icing to the cake, just think twice, why would samsung add a additional battery for?? Heheheheheh
just my 2cents, i hope i dnt offended anyone
