For those of you who are more inclined towards utility than fancy stuff, then 2100 is the one for you. I bought one for 5000 from the grey market, and there did not seem to be a better buy.
2100 incorporates all the grreat features of the trusty 3315 at the same time gets a sleek look. The display is simply great, with the higher resolution.
There are cheaper phones fro Siemens and Alcatel but somehow since most of us are accustomed to the ease of use of NOKIA phones youll prefer this set to other brands
If I had to pick some cons Id say that the battery-time is a bit low compared to others.
A word of advise is that better got for the grey market thing, cos the one with bill and warranty comes to around 6500.
Just be careful while choosing your set. Good sets are those which are made in Europe, viz, Hungary, Czech Republic, Finland, etc
Check the serial number of the phone with the one on your box.
