i view the volatile state of virtual data as a good thing, we used to think that Egyptian hieroglyphs had some mystical meaning, until we found that most of it was accounting and taxes, the same with norse runes, what people once thought was a magical inscription on a sword was actually the name of the owner, perhaps by preventing the future civilizations from knowing our day to day BS, we can maintain some view of us in a positive note, instead of just a mundane one
as Djinni pointed out, there should be some knowledge to pass down to future civilizations, but should that really be snooki's twitter feed? personally i would like to see a more volatile data system, where non valuable data (90% of the internet) is destroyed after some time, yet things related to science and culture are preserved
as for the actual media used, right now there is a shift away from optical media within the computer community, few people are buying bluray drives, i think that in a few years operating systems will start to come from a kiosk at a store where you plug in your usb flash drive, and it gets flashed with the OS, or is simply sold on a USB drive (this has proven wildly successful in china with bootleg copies of windows) most other software will be downloaded from a server
also, i think the days of loading up your computer with large capacity drives are numbered, solid state technology may never reach the huge capacities of a hard disk, but it doesn't have to, currently networking technology is at the point where you can stream your own videos and music from your own personal server, in a few years perhaps we can all be running 10Gbit switches and store our games and software on a server, leaving only the OS for local installation
