    So I am getting an MBA with Lion, and I am planning to update to ML via up-to-date program. The question is, will I need to perform a clean install of ML, or it is not necessary for a new machine? I just don't quite get the upgrade process in OS X, although in Win it always formats the system drive when installing.

    Stop thinking in the old "Windows" way. :p

    Do the upgrade as per normal - no clean install needed. :cool:

    It won't wipe anything - it just updates all Lion files.
