I bought Nokia 3310 1.5 years back and the simple reason why I bought this model is the fact that Nokia is the number#1 brand in cell phones and this model provides the best value for money!.
The things I liked about 3310 are:
1)It provides the best price/performance ratio amongst all its competitors
2)Its sleek, sturdy and light
3)Provides real good sound clarity
4)Provides all the features necessary/essential
5)Has a very good battery life and talk time
6)Provides 1800mhz operation, so its not a problem even if a new operator comes in ur city
Well, i dont dislike anything about it and thats the reason why I am still brand loyal to it!;-)..even after 1.5 years, but the only thing I regret is that the prices of 3310 has crashed now, and how I wish I could buy it again!...
