I just ordered a the 13 inch rMBP with 16 gb of RAM and the 2.8 GHZ processor 4 days ago. I saw that they just refreshed the lineup with a faster processor and was wondering if it was worth it to upgrade to the 3.0 ghz processor (it would come out to the same price on education pricing) or ask Apple to refund the current difference in pricing ($180)? I will use my computer for mostly school stuff, music and maybe a little bit of minimal stuff in iPhoto. (The 16gb of RAM might be overkill but I figured that it would be a solid safeguard against possible future RAM needs). I plan on keeping the computer for at least 4 years and want to make sure that I invest in something solid. Thanks!
