I had bought a Sony Ericsson K810i in Aug 2008 at Rs 17K.
Pros: The 3.2 MP camera with quite a bit of camera features.
Cons:
The sound quality is not so good.
The piece is very delicate and the screen and lens are very naive - Need a cover but that is not available in market.
The headsets are not the plastic coated ones as in Walkman(W) series and also comparitively Nokia headsets have Play/Stop, Rev/FF and Next/Prev songs buttons but these dont.
The camera is good but now that we have 5 MP, at a lesser cost than I had bought my piece, I feel that I should have waited a bit.
Its seems that this wasn’t a popular handset - esp there is not plastic cover and I have asked for these in about 60-70 shops till date. I found in one shop its cost me Rs 50, against the usual 20-25 bucks and it broke on the 3rd day itself.
So, my advice check the new 5 MP camera phones and folks in India wait for a couple of months after budget- it will save you about 20% of the amount.
