There are newer ones with physical buttons.

That's what your nose is for. (I'm quite skilled at advancing or going back by gently tapping the kindle against my face. It helps that I'm very nearsighted so it's kind of already there)

Really wish my 1st gen Paperweight had split forward and back buttons on the right side.

But then I also understand that'd increase the price by 10% and only help right handed people with weak hands so... c'est la vie.
