I'm 54 and can quite honestly say that ebooks have re-energised my interest in reading. I started reading on my computer a few years back, then got a Rocket reader [which I still have and use], then a CyBook first-generation. I'm now trying out an Asus EEE PC, but will probably also get an e-ink reader shortly. I love the portability of ebooks and the ability to choose your own font and font size - very important when your peepers start to fade. In the beginning was the word, but the word wasn't very widely spread so I was mighty glad when websites like Fictionwise started to show up.
What still excites me is that although I have shelves groaning under the weight of pulped up trees, I could fit all of those texts and many thousands more on a single disk which I could carry around and read whenever I want - blimey
Technology for it's own sake never really interests me, but ebooks and their associated technology -there's something worth having. Knowledge and pleasure in abundance whenever you want and wherever you are - without being hindered by the incumberance of the dead, sacrificial weight of once beautiful living organisms.
