I've been reading a bit about the Macbook Air now since yesterday (when it came out). A question I have is.. does it matter of a SSD is connected to a PATA connector vs. an SATA, ExpressCard, or USB 2.0 BUS? Apple hasn't said how the SSD will be installed or connected. I assume that it's a simple switch between the 80gb PATA drive and the SSD. I know some of these questions won't be answered until their in the hands of a reviewer or someone willing to share their findings.
