"1. As I type, my Air has been shocking my wrist. Sometimes it is just a small tingle, other times it hurts very badly..."
This occurs only when the power adapter is plugged into an ungrounded AC outlet, and the computer, right? Use the 3-prong grounded AC cord that came with your power adapter, and the problem will be solved.
The power adapter places one-half of the line voltage onto the computer ground (and, therefore, the metal computer case), at a very low current. It's safe, but disconcerting.
I checked the serial number of my Air according the website.
The information is as below:
Production year: 2008
Production week: 08 (February)
This Air has the same problems as you said. I also feel very sad for it.
I want to deliver it to Apple, but you know, the repair condition in China is still very poor now, so I will not send it only if it works at the most time.
My Air sometimes freezes when running Apple Hardware Test. What about yours?
I find that if I do not use the power adapter, it seems the freezing disappears? Is it same for yours?
You could very well have an internal electrical problem above the grounding mentioned. I think that you really need to take or send it in for a check. I seriously doubt that anyone would tell you "that it is only intended for trips". I have every laptop in the line and my air is the most reliable and my personal favorite.
