AA means they don’t have to handle battery replacements; and it’s not too-too hard to get rechargeable batteries.

I would prefer batteries in machine, too; but this does have some sustainability and repairability (by not needing it) advantages.

You're right that it's "not too-too hard" to get them, but it's also "not too-too easy" to actually use them in comparison just plugging a USB-C cable into the device. The process you will have to go through to recharge this will become incredibly annoying for something that will eat through batteries as quickly as a VR headset. Think of all the criticisms Apple has received over the years due to the Magic Mouses charging port being on the bottom and that only needs a charge every couple months, this will need to be charged after a few hours of use.

I think you're mixing up the controller and headset batteries. The controllers use AA batteries and should last for potentially months of use.

The headset itself uses a rechargeable 21.6 Wh Li-ion battery with 45W charging over USB-C.

		Thanks for the correction. Still annoying, but obviously less so.

There are 1.5V AA li-ion batteries on the market. I bought a few to power children's toys and they have comparable capacity to alkaline batteries. At high currents they actually perform better.

Cost is about 10x that of their non-rechargeable brethren, but obviously there's return on that investment.

I wasn't denying their existence. I was comparing the process of opening your device, taking out the batteries, finding their proprietary charger or hooking each individual battery up to a USB cable depending on the specific variety of battery, and them putting them back into your device is more annoying than just plugging the device into one of the half dozen USB-C chargers we all have scattered around our homes.

I doubt this would be a dealbreaker for most people, but it's a choice that will provide a consistent small annoyance for users.

		To me the greater annoyance would be to have to wait until the device charges, should it lose power mid-game.

		Why would I want to go the route of having to plug in the controllers and not be able to use them while I charge them versus just swapping in a set of spare, charged batteries? Rechargeable AAs have been around for decades! It's the same setup my quest 1 and 2 have, and it has never failed me, I got 4 batteries total, 2 in the charger, 2 in the headset, I swap them around when they eventually (after a looooong time) run out.

		True, but you can just swap in a spare set of charged batteries and you are back online instantly.

The controller is the only part that uses AA. The computer/headset portion uses USB-C recharging.

I would hazard a guess that the battery in the controller will have a life measured in weeks if not months.

AA’s are only used for the controllers and they’ve got a claimed 40 hours of battery life on those AAs.

Batteries in machine leads to having to wait 30 minutes for them to charge. Replaceable rechargeable batteries means you can instantly get a full new set. This is ideal

The (now original) Steam controller used AA batteries as well. I can't say it was my favorite feature but I did appreciate that it made "battery replacements" a cinch.
