Battle of the cordless power tools begins!

No argument there.

Except that the higher capacity NiMh cells have proved to be less good at retaining charge, and have lower cycle lives than the cheaper older Nicads ....;-)

Actually the National Grid runs at a very high voltage to minimize the energy losses. Losses are proportional to current. A low current means the voltage must be high to deliver the required amount of power.

I doubt switching at high voltages is easier since arcing becomes a more important problem.
