Well, it was definitely time to upgrade the Kindle, especially at that price. With the 7" screen instead of the paperwhite 6" screen, I was expecting the Oasis to be bigger than my circa 2013 Paperwhite. Nope, overall a smaller and much lighter form factor. It's slightly wider, but that's the page turn button area, and man am I glad to have them back. Holding it on on the page turn frame is way more comfortable than any of the ways I held the paperwhite that didn't put my thumb or fingers over part of the screen.
Also, Amazon seems to have upgraded the software. After I got my account set up, it automatically organized all my books and also created subfolders for all the book series that I have. And I have a lot of them. I was wanting to do that on the old Kindle, but manually it's a pain in the ass for that many books. The lighting, plus the warm light, is better than the old paperwhite. Anyways, a Prime Day purchase that I'm happy with, especially for the price.
