> One of the things that doable "now" that wasn't doable "then" is wireless charging. I love that I can put my phone on a pad next to the bed at night and it charges, pick it up and there is no trailing wire to unplug, put it down and there is no wire to find and plug in. This is a big improvement in my user experience.

The palm pre and several early android phones had both removable batteries and wireless charging. The back panel just had pogo pins for the coil to transfer power.
