We've seen outfit after outfit trumpet their long-lasting optical storage wares before, but Cranberry seems different. Rather than promising that whatever miracle they've just unearthed will be available "in the very near future," this company is selling its wonder product right now. The so-called DiamonDisc -- which is reportedly constructed from "diamond-hard stone" -- is designed to store precious memories for 1,000 years or more, and it's even built to withstand "temperatures extending up to 176 degrees Fahrenheit as well as UV rays that would destroy conventional DVD discs." Unfortunately, each disc holds just 4.7GB of information, and each one will run you $34.95 if purchased individually. Oh, and it's only playable on "most" regular DVD drives, so across-the-board compatibility seems less than likely. The more we think about it, the more sense that whole "just carve it into stone for future generations to see" mantra makes. Kudos, cavemen.
