I've been planning on picking up a retina pro when the next update occurs, but was wondering if the current prices make this current model worth it. This week bestbuy has the 8GB Ram version on sale for 1425, combine that with the edu coupon and the movers coupon, and it ends up right around $1200. Are the MacBook upgrades usually substantial like the phone or tablet upgrades? Will the upgrades be worth $300? Are there any big issues with the current model, that makes waiting the right thing to do? I've never owned a Mac, but have had iPhones and iPads. I don't expect to do any super heavy lifting on it, besides some iPhone app development. I have a 23 inch monitor I typically use at home, so the screen size isn't a huge deal.
