I have been using till today, Sony Ericsson K750i mobile. Today I traded it for a new mobile which is Sonry Ericsson W610i. I was quite happy with K750i, but wanted a new phone. I was quite sure that my new phone will be a Sony Ericsson and a walkman series. Though Sony has quite a number of phones in walkman series, but some of them are either slider or fold phones, but I wanted a candy phone. And my search ended with W610i. It is quite a beautiful silm phone. It has great sound quality, both in built in speaker and in stereo headphones. So I look forward to walking with the walkman and listening to great music by RD.
