The Nintendo 3DS is the first dedicated portable video game system to come with a charging station. Nintendo calls it a cradle.

With its inclusion, Nintendo is nudging 3DS owners to dock their system all the time, probably to keep them from being without a charge, given that the 3DS battery could pack as little as three hours of power on some settings.

The cradle is easy to use. We got our 3DSes today — it goes on sale in North America on March 27 — and will see if this thing is a convenience or an encumbrance. Hopefully the former.

Also: check out our review of the (presumably identical) Japanese 3DS, which was released last month.
