That is fine, but I recall having to charge my rechargable AA batteries
before use, so if you let them run down without having pre-charged
spares in your pocket then it is not simply a matter of popping in
to the nearest convenience store - you will also need access to an
electricity supply, a charger, and a spare 15 minutes. So no great
advantage over a built in battery (certainly not if the expected
life of a built in battery were to exceed the expected useful life
of the device into which it is built). Of course now there are more
and more people walking round with solar panels built into rucksacks
etc which allow them to recharge their iPod autonomously, at least
during the hours of daylight.
