Yeah, that's a good point. I have barely printed any digital work, and have the usual prints for my film images. As time goes on, I'll print my best digital work from over the years and make albums, or even have photo books printed.
As for digital storage, I regularly migrate all computer files to the latest technology. At the moment I have many harddrives of multiple terabytes, but in the past it has gone from floppy disc to Imation Super disc to CD, DVD and now harddrives. As solid state drives become cheaper, my work will likely migrate there, unless something more suitable is introduced.
The importance of data migration was made clear to me when I was uploading all data CD's to a harddrive. At least ten CD's were no longer readable, and the data was lost. The CD's were about ten years old, and the so-called archival quality Kodak Gold. They were dead. Had I uploaded their contents earlier, the data would have been safe. Now I have multiple redundant backup drives, and I move to bigger and bigger HDD's as time goes on.
