Well, that sucks. I mean, it really REALLY sucks.
I know it may seem odd to many, but when I think about my game systems, I do try to think in terms of still having them like 10 to 20 years from now. Now, granted, there's no guarantee how long they will work and what parts will be available long after they are no longer the current system. Plus, by that time I will likely be playing what the current systems will be in the future, and therefore will play the older ones here and there.
But none the less, I prefer the concept of a removable/replacable battery. It is possible that years down the road, 3rd party companies who are aiming fora niche market may make replacement batteries for the controllers (not completely unlike the wave of generic NES systems that have come out recently to play original NES games).
3rd party companies may still make products to keep your old systems running.
Plus, with Xbox 360, the worse case scenario is that if there is no decent rechargable batter options, you can still use the standard AA's. Its not perfect, but at least it will work.
So, not being able to replace the battery really messes up that plan. It's fine that the battery is inside of the controller. But it would be nice if it could easily be removed with a screw driver or something for replacement, and it would be nice if AA's or some kind of standard battery could work as an option with it.
