I was having a chat the other day, and found me and a mate had different opinions here. Personally, I prefer my mouse, controllers etc to have sealed, rechargable batteries so when they die, I can just plug them in and carry on going.
I find the removable battery option to be really irritating, as I NEVER have batteries just lying around, so when something dies I have to go to the shops, BUY some batteries and swap them out.
What do you guys think? Do you prefer sealed batteries? Or a desk full of AA's?
