The replacement for the Supper Mini Keyboard is the Mini Slim Keyboard, which isn't as fun to say as the Supper Mini Keyboard, but at least it tries.
Obviously, Supper Mini (and related) Keyboards are not for serious typing, but extremely handy for keyboard shortcuts while drawing on the tablet. I also got a second one for the primary computer because in my current one-handed situation, for situations where I need to press keys, they are actually less straining to type with using one hand since the hand doesn't have to move around much.
