7" Ereader with Touch and not Buttons

I have a Kindle which has a 6.8 inch screen. I've been wanting to pick up another ereader, but I don't want a smaller screen. I'd prefer a 7 inch screen, since that seems to be closest to the Kindle. I've been looking at Boox and Kobo readers, but all their 7 inch screens have hardware buttons rather than touch. I have not found a 7 inch screen with touch. Does anyone have a recommendation, or am I stuck with hardware buttons?
