I broke down and pre-orded the 15'' Pro with 2.9ghz and Radeon 460, but I didn't upgrade the storage. In the past, it always seemed pointless when you could buy a bundle of externals for that same price as the larger SSD drive option. Right now I have 512 and have 200gb to spare. But, I'm having second thoughts because of the lack of ports and the need for dongle everything, I'm wondering if it would be better off storing more on the hard drive and icloud from now on rather than relying on connecting HDD's whenever I need. I'm a grad student in fine art, so any given time I am bouncing between safari, photoshop, light room, word and keynote. I'm going this route from an iMac at present because I'm really getting tired of being tied to my desk 8-10 hours a day, and in light of the new P3 color space and LG5k option, this seemed like it might be a better route. But being mobile also means I won't be sitting in front of a stack of hard drives all the time. The cost to go up to 1tb is $360 for students, is it worth it for another 512gb? Opinions?
