Today’s Kindles are, of course, enormously better than the bulky first-generation ones that cost $400 back in 2008. (It was still before the mainstreaming of smartphones, and these Kindles were miraculous).
One thing, though, I miss enormously from the first-generation Kindle and that’s the automatic page-turn function. One could play with fonts to make it coincide with one’s reading speed. After all the tech advances since then, it would be great to see automatic page-turn regulate itself through learning from your reading patterns. But the only Kindle that even has the page-turn at all is the ultra-expensive waterproof model. As if people were desperate to automatically page-turn under water.
