Thats the best part of AOSP...you don't have to OC. But just to know that the developers have come up with a way to do this is awesome. I'm excited to see the progress of AOSP. Some people want to get every last ounce of performance out of their phones. Some people like to push the device to it's limits (after all, we did spend a pretty penny on these, why not). Most people don't buy a Mustang to drive it 30mph.
But you don't have to. If you wanted, you could download an AOSP rom and customize it to look just like stock, you don't have to utilize all the features. I'd just rather have a rom that is always being tweaked, and always has the newest exclusive features. To me, that's what makes AOSP (or AOSB in my case) different from GPe or Sense, the rules and parameters are tossed out the window and the OS is rewritten.
AOSP Exclusive Features: Circle Bar, Profiles, Halo, Multiwindow (minus Samsung devices), Hover and Pie with 2nd level. Man, what would I do without these custom features. Yes you can get a few of these if you DL an app or two...but why do that when it could be baked right into the operating system and run even smoother with less battery consumption?
Rock on AOSP, AOKP, PA, Liquid, AOSB, Carbon, AICP, and all the other different flavors of Android!! Rock on!! Lead the way...Google will catch up once you perfect it...they always do!
