Mine, 3 month old, is in prestine condition apart from a few microscratches in the chrome cameraplate. Always naked.
(On A side note I managed to bring a drowned 800 of a colleague back to life. After it had been dropped in a pool of water on a Saturday I got my hands on it on Tursday and it was litterally dead... No pulse whatsoever!
I thought it was gone for sure so I thought it would be good pratice to take it completely apart. While I had it complety disassembled I carefully dried away the remaining water (yes there was still water inside it) and left it to dry a few hours.
Then I reassembled it and to My surprise I got a small beep when I connected the battery, so my hopes where going up as I finished the assembly. I then connected the charger but it was still silent.... No reaction.....
But then after 5 minutes on charger I saw a battery icon and after an additional 10 minutes it actually booted.... But then rebooted, and rebooted.... About 4 times and then it settled by itself. Then I could start to explore the phone and it was a mess. Partial old data was still there and some apps where partly gone. But a simple hard reset brought it back to life

this is two weeks ago and it is still running flawlesly, much to the surprise of both me and the owner of the phone.
He did everything wrong after the initial accident, trying to start and charge and left it assembled. For 3 full days.
I was quite possitively surprised of how well the modules was fitting together again after the operation. I is quite obvious that Nokia has many years of top notch industrial design behind them. )
Very sturdy design!
