I've been waiting for a new rMBP all summer, and it's still not out. It looks like it will be out around September/October. I'll be leaving for university in a week and I won't have a laptop with me, only an iPad. I would get an external hard drive for my rMBP for back-ups and additional storage, but I thought I should get one now in order to have all necessary documents and other files ready with me when I get a rMBP in the fall. This way, I wouldn't have to go back home just to transfer everything to my laptop. I've been looking for one on Amazon and this one seems like a good option: http://amzn.com/B008S4TGDM. The thing is, it's been available on Amazon for over a year. So is worth it buying one now? Or is there some new technology in the near feature that could improve portable external hard drives in terms of speed and size?
