I could go on.
And despite all that, they're priced as if they're in some way equivalent to the real deal. I've tried and failed to make the jump via Kindle and Kobo, and until such times as pricing on the major stores reflects the eBook's status as an inferior, vastly cheaper to produce knockoff of the real deal, I won't be tempted to buy any more ebooks (the price difference should be closer to 50%, not 15%)
Another aspect as an IT guy is that my ability to relax and focus when holding a computer is vastly reduced over a paper book. The limitations of paper books in that sense are actually a feature. I can't search, bookmark (without folding a paper page corner), 'browse', play with some half-baked eInk web browser, switch book etc., all of which are real focus problems I suffer from.
