Agree! Meta does offer a battery head strap as an option but I did the math and it was under powered and over price compared to any of the 3rd party options.Apple doesn't offer a head-mounted battery solution at any price but I expect that they'll be forced to.
The great advantage of being the most popular device is how many 3rd party options so we have a choice.
Anyway, should be interesting on what Apple says in the Q4 earnings report this evening. I'm sure there will be questions on it. Regardless of the Gen 1 success or failure, at least they have introduced a new product to the Apple lineup. Shows they are not growth dead money yet. Apple is my second highest % investment but I have been selling it off over the past year.
