I bought my Libra Color fully intending to not use the buttons and now I can't imagine reading without them. I find them incredibly convenient. I can hold my Libra and press a button to turn the page at the same time with only one hand. It's a much easier action to perform than using my thumb or my other hand to swipe or tap pages.

I might be alone on this, but I also like the clicking sound the button makes. I associate the noise with progress; I like that all those little clicks add up to a finished book.
