So, I usually make copies of all the various install CDs that come with a new Mac and use those while keeping the originals in the box. It's been even easier lately as they have moved to install DVDs, which means less burning. Tonight, however, I was shocked to find that the install DVD for my new 15" 1.67 Superdrive weighs in at a whopping 7GB! Not only does it contain OS X and the various PB specific apps, but iLife '05 as well. ALL on the same disc. I suppose this is a dual-layer DVD, which means I won't be making any backup DVDs of it anytime soon.
