I can't wait any longer for a new computer, I have been waiting since December for a new iMac. I want together a newer Mac so I have narrowed it down to a MacBook pro over a 2011 27 iMac. Should I get the retina 15 MacBook or the regular MacBook pro? I will use this MacBook pro as a desktop replacement. I worry the retina will have first generation problems while the regular MacBook might be more stable? Which MacBook would you get, thanks!!! Please help which 15 MacBook would you purchase????
