Leopard's October release date seems like as far as an eternity and a day to the OS X Geeks. But they can get their preorders in right now on Amazon.
The smarter move: Put 128 dollars in a bank account now, and let it accrue $2 in interest. Bam! Two-dollar discount on Leopard when it ships. (No, I'm not a financial adviser.)
