How many of you have gone from the Air to the Air 2 and are glad you did? What made the experience better for you? I've read lots of comments from people who have great things to say about using the Air 2 with their birds. I'm trying to talk myself into upgrading to the 2 and Best Buy has the 128gb version on sale for $100 off right now. I just missed Staples $150 off sale. Thanks for your time.
