As far as the handsets in this range are concerned, this one is one of the best. You will only feel the slow hardware when youll play demaning games or run heavy apps. The OS is very fast and light and everything opens up in a flash and the interface is lovely better than android. Youll actually not feel any difference from the 710 nad the 800 as far as the basic use is concerned. At the present price, its better to buy a lumia 710 which is priced just around Rs.2500 more than this one.
The main problems with this handset (actually with the Windows phone mango OS) are:
No mass storage mode. You have to use the zune software on your PC to transfer files which can be a little frustrating.
Bluetooth can be used for everything except file transfer.
Frankly speaking, this phone is better than most in this price range and Nokia the most reliable company as far as mobiles are concerned, but I find it to be a bit slow with 800MHz and 256mb RAM but thats the best phone u ll find in market with a price range around 10-11k.
