Im just curious how much you use one device compared to the other, and why you choose to use that said device more. I recently purchased a retina iPad mini because since I'm in grad school i thought i would use it for reading pdfs and using it in class to highlight power points. However, after having it for two weeks, i noticed i was barely using the thing for school and it was mostly becoming a device to use at home as a media consumption. This isn't bad by any means, but my macbook pro was just better for me in the school setting besides reading my notes. I ended up returning the mini just cause i needed the money for a different purchase and it made me realize maybe i would need an air to actually take advantage using an iPad for school actives. Plus since i was mainly using it for home anyways, the real estate of the bigger screen would be better.
