Our Favorite Digital Notebooks Are on Sale for Black Friday

These handy e-paper devices let you write notes, sketch ideas, and even read books—and they're on sale for Black Friday.

I love a digital notebook. I write about them all year long here at WIRED, and it's not often my favorites go on sale. (Or for any to go on sale, besides Amazon's own sale events.) But this year, for Black Friday, multiple digital notebooks I love are on sale for the biggest sale event of the year.
