So I have an iPad 4 that has worked really well and is in good condition. I've been toying with the idea of upgrading it to an iPad Air 2 and was curious if you guys think it would be worth upgrading. Besides the obvious differences in form and weight will I see a significant difference in the two models? Its not something I feel like I have to do but was really thinking about doing it to get one with more storage space (I have the 64GB model of the iPad 4 now). Does anyone have any thoughts on this?
