Hi all, since they are roughly the same price refurbed and they are going to be used for a little bit of business but mostly home use which would you go with? Im not sure about the RevA from what I have read on here with the glitches in the video cards. What kind of experience do you all have, I am going to order this today and its my first Apple with the exception of my iPhone. Thanks in advance for helping out a NooB
