Same thoughts here
Very similar thought process. Recently sold my Retina Mini (2) in anticipation for the spectacular Mini 3 which, as it turns out is non existent. I also purchased the 6 Plus simultaneously to selling the Mini, so got a chance to test it as a "quasi" iPad replacement. It worked very well and in fact better than the Mini in some respects (see comments on video while traveling below). However, as good as the 6 plus is, I still much prefer the iPad for general use around the house, in hotel, etc...
So, I decided to replace the R-Mini with the Original Air (after also considering the 6 plus).
Since I have the 6 plus now, I found that I really like it for videos while traveling on plane....I travel each week for work.....used to use the R-mini for this, but now prefer 6 Plus (portable, 16:9 aspect, amazing picture). I also have a 15 R-MBP that I use for work so it's also with me each week as I travel for work.
So a tablet for me will be mainly for handy Web device in hotel, light use around the house (ie no content creation & no heavy processing). So, the value of the Air ($399 new 32 GB wifi) trumped the new features on the Air 2 for my needs. Also, at only $399 invested, I can easily sell it without taking a huge hit if it turns out not to get much use or if it gets a lot of use and I decide to upgrade to the Air (3) next year.....the one with artificial intelligence to anticipate your next web search!
The 2GB RAM is the one feature of the Air 2 I feel I'll be really missing ( ie Safari reloads, App refreshes, etc).
