Garfy over at Tale of Painters (awesome blog!) posted a great piece comparing the pros and cons of digital vs paper Codex and Army Books. Worth a read for sure, and I wanted to share my own thoughts that I posted there in a comment:
I have Dark Angels, Chaos Space
Marines and now High Elves on iBooks. I bought Chaos Daemons hardcover
(Nurgle!) and I regret it.
- the ability to tap
any rule/ability and see the details of how they work is invaluable -
especially for an infrequent player like me.
- it's incredibly fast/easy to navigate
- it stays up to date with all corrects/errata etc
- images are gorgeous
- can easily carry multiple codexes around without back pain ;D
- you can buy it at 11:43PM on a Sunday night if you suddenly decide to play a new army - without leaving your house
- as you said, can read it in the dark
only downside for me is the same as yours - can't sell it when I'm done
with it! BUT - I currently have a few mint condition latest
codexes/army books and can't find local buyers for them. I suspect there
is low demand because people often buy the latest books out of
hype/buzz, and also frankly they can be pirated. So selling it on is
decreasing as an issue for me.
Lastly: I'm not sure "can't get it
on Android" is a negative for the digital book. It's a negative in
terms of GW not servicing demand, but it does nothing to detract from
how awesome the iPad version is, and android users can buy the physical
copy so they aren't losing anything. I guess what I'm saying is it's a
negative but not in the sense that "you bought it and are not
satisfied", per se.
I think I'm done with paper army books and Codexes.
