I would like to get myself a macbook pro 13", but i would like to have a 7200 rpm harddrive. In the apple-store it is not possible to configure this and i would like to know if there is a technical reason for this? Is it because the 7200rpm hd gets to hot and the and macbook pro can´t handlethanks it? - I wouldn´t want to put the hd in it if it´s going to break down :-) then i´d rather go for the 15". Thanks...
