It took me several years before I made the cognitive switch to preferring eBooks for large, complex, dynamically accessed textbooks over the paper variant. For the first few years I actually couldn't stand trying to read stuff on my laptop versus a nice healthy paper text book (of which I have about 4 boxes that I've incredibly carefully curated down from around 10 boxes). And even attempting to read them on the crappy kindle technology and laggy ipads just sucked beyond belief circa late 2010. It was probably around 2012/2013 that they became my preferred platform on Laptops. Two things probably changed things - SSDs became commonplace, so load times were instant, and, EPUB/CHM readers got a lot betters - allowing quick hotkey movement back/forth. Now, laptops work great - but tablets (in particular, everything I've tried on the iPad), still lags horribly for textbook reading (though they are great for longform prose - I devour books on my iPad - but it's not clear that the iPad is any better for reading fiction books for me than my iPhone - and I suspect the iPhone 6+ is going to replace reading on both in short form for everything except magazines/comics). Recently, I purchased the Oreilly 5th Edition "Learning Python" and almost laughed. (A) The book is entirely infeasible to bring with you on a trip, (B) I actually had a hard time navigating it, compared to the electronic version which gives me the quickly navigated TOC on the side. And, the deal breaker - I carry about 30 commonly used textbooks with me on 9 month+ international engagements, all the time in which I'm constantly moving from country to country. It's hard (but I guess possible) to imagine how I might do that with physical textbooks (Just keep shipping them to the hotels I'm next moving to, and hope I'm there long enough to meet up with them). But I can think of no conceivable scenario in which I could be using these textbooks on the 22 Hour+ flights that I frequently take. I'm willing to wager I'll never use a physical textbook again.
