Mine came via UPS yesterday, and my wife said she was fine with her Air 1. After a few minutes, I showed her the laminated display. She sat there for about five minutes, and told me to order another one....LOL! She just picked it up a few minutes ago, on her way to a convention.
Battery life is good: 46% with 8hrs 20min usage, 18 hrs 25 min standby. Mostly web browsing, with brightness set to around 40%. Oh yeah, I did use Google maps for a while, to look at the terrain around her convention....and around some other places.
I was a bit concerned when I noticed that the Air 2 could be flexed last night. In fact, I woke up feeling a bit uneasy about it. Using a surface I know is dead flat, and a plastic drafting straight edge, I was surprised to see that my Air 1 had a concave bend on the screen side, and the Air 2 was nearly flat. My Air 1 didn't seem to flex much last might, but it certainly did this morning. It's no longer an issue, and I'm loving the thinner size. The Air 1 feels thick now...
The terrain around her convention? Are you a sniper?
