FWIW, if you get the Air with 8GB or RAM, you'll actually have ~100GB of free space when you first boot up.

If you get 4gb ram, would you get slightly more free space when you first boot up the mac OS?

The sleepfile for hibernation is stored on the SSD, and its size matches the amount of RAM you have.
