Choice that ends up costing you additional money, and therein lies the problem. Microsoft ought to include a rechargeable option with the controller and then give you the choice to pick another of your own accord and of your own expense. But instead if you want something rechargeable, you either have to buy a pack of Eneloops and a wall charger (roughly $20), or a Play and Charge kit (roughly $25), and that's the shitty bit. The fact that Microsoft is too cheap to throw in a Play and Charge kit even with their $150 controller says a lot.
Beats having to buy a nee controller like I'll have to do with my DS4 because the connector used to charge the battery is broke. 75$ down the drain :/
