O.P. My current MacBook Pro (non retina) is out of lease (notebook for teachers), so I need to replace it. I mainly use productivity apps like ms office, safari, etc but sometimes use adobe CS6, Photoshop, dream weaver, etc. I cart the lappie around from the office to the classroom, around the class, and at home connected to an external monitor. I also have an 27" imac at home that I use for work. Currently 110gb is used on my laptop. Here comes my quandary, MBA or rMBP? - Current MBA, 1.3ghz core i5, 8gb RAM, 256gb (AU$1448) OR - Refurbished rMBP Feb 2013, 2.6ghz core i5, 8gb RAM, 256gb (AU$1489) OR EVEN - Current refurbished MBA, 1.3ghz core i5, 4gb RAM, 128gb (AU$1059) I know that the MBA would be more portable, but for pretty much the same price would it be worth it getting the previous gen retina MBP? Please help! Thanking you in advance.
