    I want to minimize clutter, fragmentation, lost files, system performance, & I think a clean install is the way to go unless this isn't an issue. Anyone?

    Also, can I install Mountain Lion on my other laptop for free since my new Macbook Air is eligible for the Mountain Lion upgrade? Can I just "log in" & install it or is it linked to my laptop/serial number.

    If your machine is working okay now, there really is no reason to go through the hassle of a fresh install.

    After you get your activation code redeemed, Mountain Lion will show in the App Store app under your purchases and you can then download from there to a machine. It is linked to your AppleID and not a specific machine.
