I will be super annoyed. But I also just won't buy another Kindle if they don't have buttons. I also have a kobo with buttons that I like, so I'd just get another kobo with buttons. Though e readers don't seem to be affected by planned obsolescence like other electronics so I won't be buying a new one for a long time anyway.

Wooo Amazon listen to my opinions even though I'm not going to buy your stuff!

Sigh, I miss phones with physical keyboards.
