so ive been hearing around the tubes that the macbook pro i7 and i5 have been over heating... has the issue been fixed? if not does it overheat less on thev i5 then the i7? or are they about the same? im thinking of getting a mbp 15" i7 as an alt comp to accompany me when i cant use my quad core pc. so ill mainly use the laptop on my lap and such and i dont want it over heating while on me.
