I whip out the Kindle when I want to blow a Saturday breezing through the latest John Sandford cotton candy or awesome-seeming fan fiction, and I read most technical books and my Instapaper backlog on my iPad. So maybe my desired set of Kindle features is smaller than the average Kindle user, or maybe this discussion is proof that I have no idea what the average Kindle user wants.
- I've owned my (4th-gen, non-touch) Kindle for ~9 months, and it has held up just fine. Maybe if/when I break it, I'll wish for more robustness.
- I've never lent books; maybe I should!
- I haven't been without power for long enough to substantially discharge my Kindle's battery yet. I went to Belize for 9 days with it and had power the whole time, although I did more diving than reading ;-)
- Nope, I've never longed for random access. I've flipped through paperbacks before, but that's a feature I can easily live without.
- Nope, I definitely don't miss color. When I want to lay back and feel like I'm reading a little paperback from my neighborhood bookstore, I reach for the Kindle. When I read a textbook and inspect diagrams or want to look at pretty pictures in Flipboard, I grab the iPad.
I'm just weird with tablets though, so this data point may be worthless. I've considered buying a Nexus 7 (or its rumored successor) just to lay in bed and read code, and the official GitHub app for Android is the best tablet code-reading experience I've found.
