It helps in a pinch if you’re on a really long conference call and the batteries start to run low. I’ll pop one briefly back in the case to top it off and not have to miss anything said.
GP said they "can't be charged while being used". Which is categorically incorrect. They can, and on the scale of Things That Are a Big Deal, it's an 0.3 out of 10.
They can't both be used, and c'mon; is this really a debate? You cannot use _both_ of them and charge them at the same time. The best experience comes from using _both_ of them simultaneously. So, it's a workaround. It's fine, it's whatever, but it's also silly to get haughty about it as if there were no impact whatsoever.
>I'll just address this point, because it is categorically incorrect and something many people misunderstood when they were first released
