Surely this argument is mute, we all know that overclocking a device will reduce the life of the CPU, the try crux of the problem is by how long. Anyone who has ever owned a pc running a sempron proccessor will know that overclocking just means more noise from the cpu fan.

Every phone I have had lasted for more than 2 years easily, my k800 is still going, now I didn't overclock the cpu on that and I assume that the phone will no doubt beceome defunct technology wise before it dies, so if I overclock my n900 and it dies in 4 years time, yes I reduced the battery life by x years but as Im sure many people on this site will agree is come the end of those four years some new nokia smart phone will be about and an upgrade to that will be in order... bring on the overclocking etc. and so the cycle repeats.

Also Im sure there is a thread somewhere on this site monitoring the impact of overclocking...
