I had an ipad 2 (full size) at my old school and pretty much used it as my own. Now I'm at a new school I have an ipad mini. It's ok, but it's all linked up to the kids ones so I can't use it like I used to. So I'm considering getting my own ipad. We have an android tablet and I use my android phone all the time, so it's really an ipad I want. I don't want a mini as I really prefer the full size. Also, I have a very nice radley case for it, which I used to have for my old school one. So, which ipad should I get? I don't need masses of memory so a 16gb is fine. Is the extra expense of an air worth it? Would an air even fit in my old cover? Also, where should I buy? Is online with Amazon usually the easiest or an actual apple store? I'm going to London next week for my birthday, so would be able to go to one. Help!!!!!
