The 32GB Signature Edition is the newest model of the Kindle Colorsoft, and reading digital comics on it is the way to go. The 7in. glare-free display helps comic art pop, and you can even bookmark and color-code panels with different colors. A single charge lasts up to 8 weeks (yes, weeks), and it's waterproof, making it the perfect pool or beach day companion. If the Kindle Paperwhite (which is also on sale for Prime Day) is the best way to read books digitally, the Kindle Colorsoft is what you're looking for when it comes to high quality digital comics.
If you're a Kindle Unlimited subscriber, hundreds of comics are available for you to browse and dive into. I prefer the tactile feel of turning a page and displaying graphic novel spines on my shelf (and let's be honest, the smell of a brand new omnibus), but I can't deny the convenience of reading comics digitally.
Of the available selection, I'd recommend their Batman library, as it contains some of the community's agreed-upon best stories, such as Batman: Hush and Batman: The Long Halloween, some of my personal favorites.
