I used to have a 3650 which was nice, but now I have a 6600 and this mobile looks really great. I have only one remark about it. Anyone also noticed the audio distortion (loud click) at the end of video and plain audio files? I didn't hear this on my 3650. It is very noticable in a silent environment, which I find very annoying, especially when a short mediafile is playing in loop. I went back to the store to ask if this is normal and they gave me another 6600, but still I can here the same audio distortion. :-(
