I've slightly updated the hardware evolution diagram:

Changes since May:

- added "Buttons" as user input method, praising their reliability,
  and admit that the slider performs poorly in practice.

- also extol the brutal efficiency of killing RF by grounding VDD

Regarding the slider, there's still a chance for saving it: Dave
has two 2014 (CR2032) boards, courtesy of Canaan, to give to
anyone who'd want to try his or her luck with making the slider
work acceptably. The firmware still supports buttons and slider,
with a simple switch in DEVCFG.

So, if you like sliders, have an idea for how to harness that
messy analog data, and want to get your hands on one of the rare
2014 boards, now is the time to step forward.
