The Good & Bad
Good
In OS X we're able to freely change icons / resource files. So if Apple stupidly retardizes all the icons, it's simple to use the custom icons I presently use. Unlike iOS that still doesn't have any way for us to use custom icons of our choosing. I emailed Apple a great idea at the official feedback site, about using iTunes for custom icons, similar to organizing Apps in your iOS device through iTunes, but Apple hasn't listened.

Bad
If Apple goes with excessive whiteness, like the iOS 7 music player, I am going to spaz right out. Jony, if you read Mac Rumors: Please don't!
