I agree with some of what you say.

I hope Nokia will supply existing users with a replacement back to take care of the reflecting flash problem, as well as improve the firmware. Pictures without perfect light have too much "fuzziness" for want of a better word. Today I took a photo of a black football jersey and that had this fuzziness as well, in normal light in the daytime. It doesn't seem to handle black very well.

I've had freezes as well, and I don't understand why a web page I've kept open for 6 hours will start "not responding". It's just a long blog article with 100+ comments. There's no updating involved.

The album artwork will only show up if you have separate picture files in the directories. It shouldn't show up if it's embedded into the music file. This is not necessarily a bug, the phone is just showing every single picture in the phone. If you don't want to see them, make sure you choose "camera folder" or something along those lines.

Try resetting the tracker for your music. I have around 16gb worth of music on my memory card. I just reset the tracker overnight once and it's picked everything up. Having said that, I've never had the problem you've had. Only if I try to look at the media player straight after disconnecting from the computer, which is understandable as the phone is still finding the changes made.
