That's the case for me as well. I love the old wireless keyboard & trackpad that take the AA batteries, because I can swap them over so quickly, no hours of downtime due to recharging. Same with my Bose QC25 headphones, which last for weeks on a single AAA battery - I just keep a couple of spare AAAs in my backpack, and if I'm travelling it's easy to buy AAA batteries anywhere. I do have a pair of Bluetooth headphones I use with my TV, but I never use them with my MacBook Pro, I always use the QC25s (and the media control cable would be awesome, if Apple hadn't hard-wired play/pause to only work with iTunes).
