I think most of this is Amazon's fault. I buy Kindles (as well as other brands of ereaders) and I'm already very attached to the Oasis but I think Amazon is arrogant and stubborn and it annoys me enough that I almost hate buying Kindles.
I'm annoyed that after all these years and all these generations and all the improvement in screen resolution there are still only eight font sizes and few other ways to customize the look of the pages in books.
I'm annoyed that their quality control is so lacking that hoping for a good screen is like buying a lottery ticket.
I'm annoyed, and also worried, that there is so little information provided about the split battery system on the Oasis. Neither the product page nor the user guide has one word about how the split battery works -- the conditions under which the cover will recharge the Oasis, and the amount of reading time to expect from a fully charged onboard battery (not even the weeks-at-half-hour-a-day ad-speak).
Saying that it works as it's designed to work doesn't seem very sensible to me; we don't yet know either how it was designed to work or how it does work.
Well, I'm glad to get all that off my chest.
