I just love how even the simplest things like batteries are changing to make our lives easier. Now this is technology that makes sense. Plug the battery into your USB port to recharge. For $19 a pair I think it's a great buy, since Duracells cost almost that much to use.

I see this as being very handy for the traveler. Plug the battery into your laptop, and use it on whatever other e-device that requires it. It would also be a good thing if parents had a few packs of these around. toys today require innumerable batteries, and if used frequently, this can get expensive. So, here is life made simple. Everyone's got to love it.
