I know this has been debated and I thought I would chime in with my 2 cents. I had the 1st Air and just got my Air 2 yesterday. I immediately noticed the difference in thinness and even lightness. The screen quality is dramatically better imo and the fingerprint scanner tops off a really nice upgrade to the original Air. For me, the upgrade was well worth it. The Air 2 is quite noticeably faster, beautiful to look at, and very nice to hold in my hand for extended periods. I also like not having to swipe and enter a passcode. I think this is the best product Apple has made to date.
