I think it’s a smart option. Fair chance there was a LOT of thinking that went into it. For example, wondering about the characterisation of it with processing in the battery appliance. It would be “an expensive portable device with a dumb headset screen”. Could someone else sell a different headset for the device? Could they sell a Linux machine that is good enough to power the headset? Might people just want one or the other, and bitch about the cost of an ARM based mobile PC that burns up your bag because it has no free-flow air? Might be Apple releases pricy larger batteries. Or some cable that allows you to hot-swap them. I see there is a cable where you can plug the headset into your Mac for development. They hopefully considered the multi-year evolution of it, not just this year’s version.
