Amazon has finally made a Kindle you can write on.

E-Ink is used for a lot of things, not just e-readers like the Kindle and Kobo. It’s also used in supermarket shelf labels, so prices can be updated centrally, and one of the most useful uses is in note-taking devices, e-readers that support pens and allow you to take notes and mark up PDFs. It’s a niche use, but a popular one, and now Amazon is finally making a note-taking app called Kindle Scribe.

"The Scribe is a huge deal because of its modern features that make the classic Kindle appealing to both younger and older generations," Troy Portillo, director of operations at online learning platform Studypool, told Lifewire via email. "It's good for students, writers, researchers, and historians. The Kindle Scribe is perfect for users who like to take notes and annotate what they read. I'm excited to get my hands on one!"

E-Ink screens have several drawbacks compared to the screens on our phones and iPads. They are usually only grayscale (although color e-ink screens do exist), and their refresh rate is not fast enough to keep up with the kind of user interface animations we are used to.
