No problems on mine. I've had near-zero wi-fi use due to the reported bug and don't want to reboot my N900 everytime I use wi-fi. I go about 36 hours in between charges (with about 20+% life showing on battery indicator). This is with moving files via bluetooth (approx 100+mb), some phone calls and text messages and about an hour of music.

I have one stuck pixel, noticed a couple more that are extremely light that I've chosen to ignore.

I like the phone and consider it Nokia's best phone to date. IMO, nothing is perfect. If you spend enough time looking for imperfections, you will find them.
