Same here. At first the retina mini was the only consideration for me. The price and size made sense. But after trying it many times in different retail establishments and comparing it to the Air I put the retina mini down and bought an Air and never looked back. I already hate all the zooming on web pages using my iPhone. Thinking the retina mini would be better because it's bigger than my iPhone. Heck No. I was zooming every news article when trying the mini and that was in landscape mode.
For me the Air is the perfect sized tablet and the screen quality is much better than the retina mini. Besides I use my iPad for work and need to demonstrate to my clients and need a decent sized screen for that.
Over the years I've just learned with Apple and several other companies, if you don't get their flagship/top of the line product they will cut corners and dupe consumers on their smaller more affordable products. I'm totally happy with my Air.
