OS X Tiger
I bought a copy of OS X Tiger today. Sadly, Apple, in their infinite wisdom, have decided to only sell it on DVD, despite it still supporting all kinds of Macs which shipped with a CD-ROM drive. Like my Cube. Apparently there is some way of getting CDs out of Apple, but I'm buggered if I can figure it out. I can't find anything in the box telling me how, nor on their web site.
