Thanks again..
At this point of time, I seem to be more inclined to buying the N6600..
Two factors which support this are firstly,
that more people have Nokia than Sony Ericsson, and hence I have a better chance of finding software, themes, etc for it..
The second one is that I haven't used any other phone than Nokia before, and I would feel more comfortable using one..
I am also of the opinion that Nokia is the most popular mobile phone manufacturer, for a reason, and that is they concentrate on all aspects a phone should have, equally..
I don't know about SE, but Samsung concentrates on one or two featuers in each of its phones.. Like, some of them have flash cam, some have large collection of polyphonic tones, etc.. They never seem to bring it all together into a single phone..
