When i bought this phone,i know the camera is not so good.and i have enough money to buy K800i.but,when i on the phone,i in love with it.The camera quality is good.What do u expect from a walkman phone??the camera is 2MP and works better on day.The sound is very loud and clear powered with Megabass(tm).If u use handsfree,your ears gonna blow!The phone is semi-symbian(which u can installl software).It has trackID and Walkman 2.0 which is very superb.The design is top class and suitable for both female or male.with gold layers that the usual orange.
If u have more money,buy K850 or W910.but W660 is very great phone.
I've had Sony Ericsson's since 2000, starting with the T68. The W660i is a great little phone. I never seem to have a phone for more than six months as I get fed up with them very quickly. My previous phone was the W810i which I had for a record 18 months. I wasn't sure what to upgrade to, as most of the new Sony's are very similar. In the end I opted for the W660i which is essentially a 3G version of the W810i in a bling casing! It has some nice new features such as TrackID, a nicer screen, updated Walkman player and looks a little trendier. On the downside, the camera is not as good as the W810i (no flash or autofocus) and the keyboard is very cramped. I often hit the soft keys accidentally when pressing either 1 or 3. All in all, its a good all rounder and I'd reccomend it.
