Wow, the sentimentality to the printed page.
Positives? No power necessary to read, can sit in the basket next to the toilet to be read at any time. Can be thrown without damage at deserving targets. Can be used for house insulation as they accumulate over the years.
Negatives? I cannot fit THOUSANDS of publications in searchable form on a single device I can carry anywhere and can be used for other things besides reading.
Electronic forms of publications are here to stay, and if any publication wants to attract a younger audience and new customers to grow, it HAS to make the transition. Otherwise it will die as current subscribers exit life leaving an ever dwindling subscription.
If a particular format such as PDF is popular enough, the ability to read and display them will be around a VERY long time. Almost all blurbs and datasheets are in PDF form, so there is a tremendous drive to continue support of that format.
