What happens when the wallpaper is obsolete?

Susannah, soon to reemerge with a mission in her capable hands, sent email pointing to this Slate piece about digital editions of art, including wall paper that is digitally printed. I wonder about having the wallpaper, or any electronic edition, becoming obsolete or buggy. Granted, you get the Adobe Illustrator file used to generate the wallpaper print, but a CD deteriorates and Illustrator files eventually don’t open in new versions.

When I think of all the data I’ve lost over the last decade, it seems like we save less of value and a lot more crap.

Does anyone know the relative pixel value of a velvet Elvis print? So, which is worth more, aesthetically and economically, the high-res print or the crappy velvet Elvis?
