Tech ping...............
It stands to reason the Next Big Thing in tech hardware was batteries — MUCH smaller and longer-lasting using a new framework.
It struck me the progress was moribund — laptop batteries are still pretty large and PDA batteries short-lived. A few % improvement in 10 years or so.
Good to see something happening in this area. Just as wireless was a game changer for personal computing, so will extended battery capabilities change — maybe EVERYTHING.
