... ebook reader, maybe? Can't think of much physical books offer over those, barring the whole battery-life thing. Some of them even have that neat little setup where you basically turn the pages (run your finger across the screen) anyway.
I'unno. Nowadays most of what I miss when I'm reading physical text is a bloody zoom feature. I'm used to reading at around 180% zoom these days


Get a physical book of length with text that size and you probably need a trained gorilla to carry it around for you.
A nice grey text on blue background or something (yellow on black, etc., so forth, so on. Darkling has a soothing color scheme.) is really much nicer than most physical texts, too... least
seems to be easier on my eyes, anyway. Digital copies tend to be so much more... malleable... than physical ones. You're a lot more likely to be able to adjust things to taste, often with very little effort. S'nice.
... still a bit of a bibliophile, though. Lot more comfortable throwing books at people than I am the computer. Decent book can take the hit at a solid velocity and maybe tear the cover at most. Computer falls to pieces at that sort of impact.
