Hi everyone! Now that the new MBP's are out, it is time for me to buy my first Mac! I am going to be starting college in the Fall, and need a computer that will allow me to do mostly basic things (i.e. word processing, surfing the internet, downloading music, etc.). However, I'm stuck on what to get - 13" 2.66GHz MBP or 15" 2.4GHz??? Is there really any difference on the speed? Any help would be greatly appreciated! Thank you!
