Nokia Vs. Sony Ericsson: In terms of features?

in terms of applications, you must prefer nokia as most of nokia phones are symbian S60 based so you can install much more applications on them. But if you want the overall best phone, you can go for Sony ericsson as they give better camera quality, better battery backup and better sound quality then nokia.

well nokia is always a best choice we can install many softwares and most compatible with windows and customized features are awesome

If you want a good brand then nokia is the automatic choice but if want a stylish model or you want more features in less cost then sony ericsson can be chosen . In ericson you can get flip, slide or slim models but you dont have that many choices in nokia if your budget is not big. Ericson is the more flexible and customizable phone.

Nokia continues to innovate features they put on their phones. Staring from infrared, bluetooth, wifi, GPS and other stuff. Their Symbian firmware is so user friendly at least to my perspective. There are lots of 3rd party applications o download from the net. Meanwhile SE's firmware is quite difficult to get used to. Applications are also scarce. But now some SE mobilephones have already adopted the Symbian OS, this could be the start of SE mobilephones being on my wantlist.
