You can find e-readers with 10.3" displays, 227 PPI, double front-lit (warm and cold, you can mix them for the best experience, work independently), full android on the device.
To be precise, I'm talking about the Onyx Boox Note series (note 2, note 3, note air) that I picked after my previous kindles and pocketbook. It's awesome.
Android is adapted for the best experience with its unique features, you can use any application in google play, and the screen is so good in "speed mode" that you can browse the web and even watch youtube. Stylus for notes, and you can buy a "paperlike" protector for the screen.
For now, it's the best one from around five different e-readers that I have before.
If you want to take notes, there is Remarkable 2. You can check PocketBookt InkPad Color, Onyx Nova Color, Onyx Poke2 Color, and Kobo if you wish for color display.
