It's great! I think it's an awesome piece of technology that was very well thought out. But is anyone afraid the port is going to get dinged up when the Air slurps it in? I know a lot of people always comment saying why use keyboard covers, cases, etc., when the computer was meant to be used, but this makes me really nervous as I like keeping my devices in excellent condition. Subthread!: I had my MagSafe plugged in to the Mac before the wall (I know, I know) and when I plugged it in there was a pretty big shock/spark, bigger than normal. My air displayed "not charging" for a split second then said charging as normal, you think it's okay?
