I'm very confused, the author talks about having to charge a device instead of replacing batteries and blames it on Lithium-ion batteries, instead of doing the sensible thing and blaming it on devices with non-replaceable batteries.<p>The form factor of AA and AAA batteries (which the author prefers) exists with all kinds of chemistries, including Lithium-ion nowadays, you can recharge them, but while you are doing that you can also put new batteries in your device and use it immediately.
