Well I have a Mac Book Pro, its a couple years old, and it has the faster speed in it which I got upgraded when I bought it. I also have an Imac, which is about a year old, the entry level one for 1899 or whatever. Anyway the ex missus wants one of them, she is moving into an apartment and I am staying in my house but don't know which one to keep. I am a musician and like writing which is why I bought my MB Pro. I believe you can upgrade the memory for the Pro but not the Imac which is good. I mean we would have to erase and restart both to clear them if we switched. But I like my Pro, but I like the big screen of the Imac. Which would you give up.
