I just got back from the Apple Store, and I have what seems to be a new problem with the Macbook Air: The hard drive begins to fill up slowly with every single usage of the Internet. Meaning every web page accessed causes it to slowly add more space to the hard drive. I ended up having zero space left. I then decided to reformat, which did nothing. Problem happened again. The Apple guy believes (as I do) that is a problem with the SSD. Anyone else even heard of this happening. I am now going on my third machine, first one returned due to dead pixels in the screen, now this.
