I have only had my Kindle Oasis for a day but I absolutely love it!
I upgraded from the Paperwhite which is an excellent device but the Oasis has a couple of extra features that suit my needs.
I suffer from chronic pain and apart from my eyesight not being like it used to be holding a book is now a struggle. The Oasis is super lightweight and fits perfectly in my hands. I spend a lot of time in bed now so the Oasis is great for that with the flipping of the screen whichever side you lay on. The buttons to turn the page it also a big plus. The default setting is for the top button to turn the page and the bottom button to go back. I have read some reviews where this is an issue for some people having them in this order but you can change them to go the other way which is a plus. I really love the bigger screen and how there is now a warmth light feature which is also perfect for me. I don’t normally read in the bath etc but like the Paperwhite is good to have this feature if you like doing this.
Although it has a hefty price tag for me it was money well spent.
