The decision to overclock or not to overclock is indeed up to the individual user. However, that being said - I will rain down with furious vengeance on those (if any) come back here complaining they cooked their N900. Myself I flashed - checked it and went back to stock. While the speed improvement was nice, I am going to wait to see what 1.2 has in store for us before making a permanent decision on OCing.
