Hello world! After waited so much weeks now i NEED to buy a macbook pro, i'm n00b in the mac world! I'm oriented on the 13" for mobility. I'm computer engineer, my main computing needs on a notebook are coding (mainly with XCODE for iphone) and i really like to carry EVERYWHERE EVERYTIME my notebook with me. My only doubts are about CPU, i KNOW that c2duo it's ok for my needs but... a core i5... well it's really interesting At last i think to buy the 13" and, if in the future will be released a 13" i5, sell my 13" c2d and buy the new revision. Hints?
