I am not as opposed to battery power as many people on this thread, but the batteries need to be easily replaced and a standard size. Any device with a non-replaceable internal battery has an expiration date, and if you're bad about remembering to charge it, that date might come soon. A great example is my portable guitar amp, which wouldn't hold a charge. A new battery was $20 and took minutes to replace with no special tools. Plus, if a device runs on AA or 18650 batteries, I can keep some spare charged ones in a drawer or bag, effectively providing unlimited usage time. My wired keyboard will last for decades barring physical damage.
