Well, while enjoying a beautiful, sunny day here I was outside with my MBA surfing the web. I had a few other apps open at the same time like iTunes, QuickTime and Mail. Safari all of a sudden beach balls and I wait a bit until I try doing a force quit on it. After a while I still have no response and I cannot close it. So, I hold my breath while forcing a shutdown with the power button. To make a long story short, I ended up with the flashing question mark on the gray screen. Now I'm doing a remote reinstall from my MBP!
A beautiful day turned gray...
Now can you imagine that you are on an important business trip and it fails and you cannot do a reinstall of the operating system because you haven't brought your external superdrive????????
This thing is not ultraportable ...
