Why build any feature into an OS just use the apps that emulate them lol. Silly logic. It's cool that's why. It's a fun neat future. You guys think too much. Stop being haters gaddamn. you build things in the OS so they are more stable, better optimized, and could even be built into the camera software and whatnot. It would be nice. Also reading reviews for one of these apps 3D live wallpaper, lots of people complaining about general wonkyness and RAM usage and all that. Yeahhhhhhh.
Also what are one of these apps I want to try one, I'm bored. A free one of course. Aint payin forthatshit.
