I really really really want the Neo Air...but damn it's expensive. I recently ordered the uninsulated Big Agnes inflatable because I was under the impression that the Neo Air wouldn't be available until April and I have a trip or two coming before then. The BA is only 11oz (the main reason I bought it) so from a weight perspective the Neo Air isn't a tremendous improvement (9oz vs. 11oz). It'll come down to warmth and comfort, and for that I'll need to try one out once REI has them in stores. I honestly don't know how cold I'll be on an uninsulated pad...my bag is a 20F synthetic and I'm a hot sleeper. Unless it's REALLY cold outside, my bag is like an oven to me.
