you are right, but l have a reason for this, i live in Brasil, and hear don't have a apple store and is too much dificult to buy a DDR2 memory. If i buy in EUA using a ups or similar i pay $40 shiping and the price + shiping 2 times for costom. For this i wait because in abril i return to Miami.
Sorry for my bad english. The aperture is with me because a friend buy it but don't use and like to sell me, and i try it.
