How about pushing for the adoption of 8cm discs in laptops, and even desktops? With the increasing density of optical media, it's conceivable that in the future those smaller discs could gain some widespread use. I know that while Apple's slot-loading drives, desktop and laptop models alike, don't accept them (yep, they actually "choke" on them and have to be serviced

), the Nintendo Wii's does... If Apple fitted their whole lineup with drives that could accept both 12cm and 8cm discs, with either CD, DVD and BluRay/HD-DVD density, they could fit some select ultraportable laptops and/or tablets with 8cm-only slot-loading or bottom mounted optical drives... It's not like you'd want to watch full HD-quality video (either off a full-size HD-DVD or BluRay disc) on a tablet or an ultraportable anyway, right?
Why not? Of course, most DVD and CD-ROM drives wouldn't be compatible with this new "standard", but if you think about it, high-density 8cm-media would be just a subset of the BluRay/HD-DVD standard (like the 8cm CD-ROM of today), and thus, 100% compatible with every new computer or device which ships with one of those.
If there's a company that can push for the adoption of new standards, it's Apple. First USB, then the end of floppy drives... And besides, it's not like most PC manufacturers would spend much more on optical drives, as most PCs come with tray-loading models which have no trouble reading 8cm discs. It would only be a matter of waiting a bit for some settlement on the "HD standards war", and convincing software vendors to distribute software on that new media, especially by giving the example. Apple has already shrunk their product packaging, so why not extend that trend to its actual content?
Of course, with the increasing adoption of broadband connections and subsequent on-line media distribution, this may just be an exercise of futility
