^^ I agree. ^^
However, insofar as vinyl is concerned, I think FranklinRichards was focusing more on the following/collectability of the items. Vinyl has grading values, conventions, price guides, etc. Some cds go for higher prices, but it's not nearly the phenomenon that vinyl collecting is. Which is why records are still produced while every subsequent 'techonological advancement' that has attempted to replace them has come and gone, from 8 tracks to cassettes to slowly, but surely, cds.
Printed comics mean a lot more to certain people than just the stories contained within. People with collecting mentality are more interested in tangible items than bytes.
When I first posted that above, I was actually considering vinyl and all of the technological attempts to make records obsolete.
But, maybe, just like with modern records, if you buy the physical copy, you get the digital download with it. Records do that now.
