The thing about identifying as removable storage is that it allows you to use whatever music syncing tool or library program you want, and aren't locked into the universally horrible vendor-supplied excuses for an application. Files in a directory structure are a universal API that almost any program can understand and make use of.

As for the IM protocols, maybe this will prompt people to migrate to better protocols like XMPP. ICQ, MSN, AIM and all those other proprietary protocols with their ad-laden, bloated clients (which I classify as nothing short of malware) should have died years ago.
