I have no doubt that e-publications will soon be the new norm. And while the logical part of my brain may understand the reasoning behind such a maneuver, I highly doubt that the emotional part will enjoy the same fulfillment from a backlit screen, than it does now from a weathered, crisp page....
Certainly there are times when I need an answer, and I need it quickly. But for enjoyable reading, the kind where you kick back in the recliner with a cold beverage and simply lose yourself for a couple of hours, nothing beats ink in my opinion. Especially, where an old, used book is concerned. I have many such books in my collection, and each one tells another story, BESIDES the one printed between the covers....handwritten notes in the margins, a folded corner of a page, the owners name on the inside cover, the delicate, yellowed pages....all speak of events, people, and years gone by.
When a pixel can deliver on that level, then I will consider it. Until then, it's just me and that simple paper bookmark made by one of my kids when they were in first grade. It simply feels right.
