Hello, I am a Web administrator for a community college and do freelance work on the side. Currently I own a 2010 macbook pro 13.3 with 8gb of ram. A professor has come into my office and offered to buy my current MBP for $1050 (with the original 4gb of ram in it). I feel like I have to sell it, due to the trouble I have working in CS5 on such a low resolution. I (like many of you) have a problem when it comes to macbooks, I always want the newest ones and have had over 20 macbooks in the past 2 years. I am trying to decide which machine I should upgrade too, I have a feeling that $1050 for my machine, I will NEVER get an offer like this again and want to take advantage of it. I am not sure what to do, I would prefer to have the high-resolution matte screen but once configured its a mere $50 difference between 15 and 17inch macbook pros. I would just get a 27inch imac, but I require the portability so I am not sure which machine I should get. Please let me know of any advice or insight anyone may have.
