> Solid state batteries with 10k charge/discharge cycles are never going to happen for the same reasons, which are identical to the same reason incandescent bulbs are purposefully manufactured by every single lightbulb manufacturer to fail when they figured out a hundred years ago how to make them last forever.

I use an iPhone now, but if a user-upgradeable Android phone came out with a solid-state battery, I would switch.
