Not to get overly graphic here and give too much personal information... lol
I'm not a sit-and-wipe-er. I get off the seat to do my paper work. I also have limited flexibility and would find it difficult to flush with the buttons right behind my back while still seated. And the buttons are right in the middle of the tank (middle of the back).
But again, my habits are different from others and I've always "done my duty" this way. But I absolutely love the toilet.
