I bought my iPad 4 at the end of August and I'm a student so I don't have money to buy an iPad Air right now. Besides, I'm perfectly happy with my iPad 4 at the moment.
Too bad though that if I'd bought it one week later, I could download the iWork apps for free now. If only I'd known. Oh well, I have different apps for all my university work so guess I shouldn't complain. (Sorry for the off-topic part.)
