At $190, the Signature Edition is more pricey, but it adds an auto-brightness sensor and Qi wireless charging, making it an interesting alternative to the $250 Kindle Oasis if you don't care about that model's more streamlined design and physical buttons.
The 2018 Paperwhite also came in a $160 32GB version with no other upgrades, but this year that model is being replaced by the Kindle Paperwhite Signature Edition. Like the previous Paperwhite, the new model has an IPx8 waterproofing rating, 8GB of storage, an antiglare coating, and buttonless bezels that sit flush with the device's screen. Amazon also promises improved battery life for the new Paperwhite, but when you do need to charge it, you can finally do it using a USB-C charger rather than the increasingly outdated micro-USB port on older Kindles.
