Well we needed to define what bloated means. While we have always point to its size. Most of the time it is including too many things we dont need and want while the whole thing is slow and large in size.

If the app with 10GB can open in less then a seconds then i dont think many would have complained. The problem is all these apps are getting slower, even with the Hardware performance improvement, and they take up valuable SSD space.

iTunes is one hell of bloat. Because you simply dont use your Music Player to manage your iPhone! It simply does not make any sense. And telling casual users to install itunes is just making the problem even worst. The Sync Apps should be linked with your Media Player Library or Playlist. But it should not be the same app. As a matter of fact, get rid of Sync with iTunes and use iCloud instead.

There are lots of bits and pieces in OSX that is showing its age. It wasn't much of a problem when Microsoft fail to make decent OS, and Google wasn't doing Android. Now Windows 8 has a shit UI but brilliant Internals, and Android is basically a Linux with cooperate backing. Apple seems to lack enough Software Engineers for an OS internal development.
