Guy at my job offered to trade me his 15" macbook pro late 2010 i5, for my 13" late 2011 i5..... both our macbooks have 4gb. 500gb hd. Is this a decent trade?
15" has a dedicated GPU which is always an advantage.
Preference really, depends on the condition of both etc. I prefer the form factor of the 13" but I would love one with a dedicated graphics card. The retina 13" spoilt that option but the new Haswell CPU's due this year should remove some need of a dedicated card
