The touchpad of this Sony Vaio laptop is dead, the fan makes more noise than a chopper taking off, the keyboard is dying, the plastic carter is dying, my battery does not give more than 45 minutes autonomy now, and I am fed up with Windows becoming unstable. I have decided my next laptop will be one of the new 15" MacBookPro. The only question I have is the following one : 2.53GHz or 2.8GHz ? If you have any hint about the plusses and minusses, please add a comment. Is the 2.8GHz worth the price difference to build faster ?

Side note : I'll also buy one of these beasts as soon as it's available...
