Don’t believe me? Amazon has killed Borders. Barnes & Nobles looks like it’s next. We’re not far from a time when the only vendor for books are virtual stores. And we’re not that far off from a time when print books are so expensive thanks to shorter print runs, folks will be forced to buy electronic media or not read at all.
It does make one wonder about shorter print runs and whether publishing on demand can keep with the cost of mass print runs or not. I am not informed, either way, but if it cannot them it's going to be tough to beat eReaders.
