I had 7.....yes 7 macbook Air units! I ended up giving up on the idea of an Air. I'm sure i posted on here about my experiances.
All bar one unit had bad backlight bleed and there were a variety of build/QC issues including scratches....pitting....curved space bar.....poor lid fit.....wonky feet and weird patches (penny sized) of discoloration on the screen on solid colors. These units are produced by Foxconn for apple and all I can say is the QC there is pretty low. Apple design a desirable product at a premium price and then it all falls flat because they dont seem to have decent QC in place. Having had to return several ipod touches and iMac (20" white core2due) 2 macbooks 3 macbook pro's and now 6 24" iMacs I have to say I am stunned by what poor quality some people are willing to accept. We are not talking about cheapola Acer stuff here but products that are aimed at the top end of the consumer market. Don't get me wrong, I love apple's os and industrial product design but always dred opening a new product as most of the time I quickly find some sort of fault with it and have to return it. Sorry to go on but there seems to be a whole lot of bad apples out there.
Good Grief. I would have given up and bought a Dell after all of that.
