It is the only reason why my PS3 was still hooked up. I have about 40 3D Movies and not being able to use them without a separate dedicated player was a pain. Having a PS4 & Xbox One and neither of them supporting 3D was a pain as having my PS3 hooked up with all my other AV equipment just made it a pain in the ass because of shelf space. The PS3 was standing on it's side on the floor because of lack of space, but now I can finally get rid of it. So that is a big deal.
Yeah, there are some features that you would think should of been there from day one, but to me that is just more proof that MS did not plan to release the system in 2014 and due to competitive reasons, they had to launch.
So for me, I am happy when I see that they are adding basic things like low battery indicator and such. Yes, I wish it was there from day one, but the fact that they are adding it and some other stuff is welcomed.
