The controllers should come with internal batteries built in that you can plug in to recharge, saves me money on batteries, lowers the risk of destroying controller due to battery leaks, and saves environment from throwing batteries out every week

I really think that if you want to use rechargeable batteries, you get AA rechargeables and use those.
If they were installed in the unit.. and they stopped charging, which they all do after a time, we would be throwing away the whole controller.. or sending it in for a new 'internal' battery.
I'm glad that they chose to use regular batteries.
