I am probably one of the BIGGEST multitasks here and I use a 13inch macbook pro i5 8gb of ram. Why doesn't mac allow their macbook pros to have up to 12 or 16 gb of ram! I mean really the HP Envy can! *Another reason why I love the Envy and why I regret getting my expensive mac. Do you think they will ever allow this? Soon 4gb is going to go extinct for the good laptops because people are needing more now days.
