I was planning on purchasing an ipad 3 or 4 to supplement some basic laptop needs when I go to campus, but upon reading a lot of posts, the ipad mini seems to do a good job as well, in terms of portability and power. The lack of retina does bother me a little bit, but for the form factor, I think it's a considerable choice. I was thinking of perhaps buying the ipad mini 64gb wifi for now, and perhaps ebaying it off when one with retina (along with upgrades in ram and cpu) comes along in March (hopefully). I recently got approved for a chase freedom credit card, so I plan to take advantage of the $100 cash back from 500+ spending in the first three months. I figured I would buy it and then maybe breakeven or make a little bit of profit for mini 2. How much do you think the value will depreciate, by the time mini 2 hits the shelves? I'm hoping to maybe sell for 450ish, maybe? What do you guys think? My usage is also primarily for pdfs, powerpoints, and anatomy applications (and the regular browsing). Thanks for reading, and I appreciate all your suggestions!
