I'm not O/C'ing my machine - that way I can see the REAL speed of my apps and what the general populace should be seeing too.
I may well patch my machine at some point, but I've not bothered for my Pixi, Pre Plus or Pre2 and haven't really felt the need to so far.
Also, I know it's practically impossible, but I don't want to brick any of my machines - I really can't afford to replace them, even if i could get hold of them!
