K750i what you want in a phone.......... good sound quality , good reception and good battery backup with support of MP3 and FM + last but not the least 2 mega pixels camera. You will get everything in K750i. The sound quality of MP3 songs on speaker is ultimate I will say better then W 810i.
Further the phone is handy and affordable.------------------
Earlier I have been a fan of Nokia phone due to support of various application software due to simbean platform. But if you are a music lover then I will suggest you to go for Sony erric. Mobile range form K750i to upward.........
I have tried games of Series 60 of Nokia it almost support all JAVA , JAR Files. SO you can also enjoy gaming after installing these files in you K750I phone.
Now I am eagerly waiting for the launch of W 990i which I hope will be the ultimate phone of Sony Erric........................................................................................
The only drawback I found with this phone is the Headset which is not of that qualty which you are getting in Walkman series---------
