I personally can't let this one slide. I've lost research work that I did on the Air and had to start all over. Also the thought that it could happen anytime and you may or may not loose data is most troubling and not in keeping with Apple products so i think that's why a lot of us are posting more and more so that Apple finally pushes out a fix. (We hope) Also it's an embarrassment when your giving a presentation in front of everyone and your Air goes blank. They are many scenarios poeple can give why this is a serious issue that needs attention but am just stating mine. So i think if it worked for you, then that is very good an am happy for you but know the scenarios are different for a lot of people.
My solution was to be doing my research from my iMac at home which means i can only do research when i get home out of fear i don't loose data. If Apple can't get a fix, then i'll move back to the MBP, it's another solution but expensive. I would rather shell out money to use a laptop that is realiable because the headache of loosing data is much worse.
And like a user said, how do you sell the machine to another person. Lying that there is no problem is out of the question so you'll have to inform whoever that the machine is defective and hopefully they'll still buy it.
