I think this is yet more evidence that after quickly reaching the peak of inflated expectations (as mentioned in the quote, around the year 2000), eBooks have reached the bottom of the "trough of disillusionment" in
Gartner's Hype Cycle and are starting to climb into the "slope of enlightenment. Companies that develop and embrace emerging technologies must prepare for the roller coaster ride of the hype cycle. The ones that don't prepare to weather the lows with a comprehensive business model will find themselves out of business or scrambling to embrace other proven technologies in order to survive.
Now that ebooks appear to be emerging from this low point, advocating ebooks and educating the masses will only help to accelerate their widespread adoption and acceptance.
