To be fair, the Newton allowed you to change batteries with power still supplied. It used watch batteries. Switch one battery or the other and keep everything. People aren't asking for the world, they're asking for something that's been a solved problem.

Given the people still using Newtons, I wouldn't bet against them - although black & white would be the result.

The HP TC1100 Windows XP tablet had hot-swappable batteries, granted you had to put the device to sleep first, but was ultra convenient.
