Google unveils Hangouts: a unified messaging system for Android, iOS, and Chrome

I find the term "unified" in this instance misleading - they took the chat feature out of their G+ Android and iOS app and called it 'unified.' It's nothing like iMessage, and it will still require anyone who wants to use it to install a separate app, and likely to get a G+ account.

Article says they are replacing Google Talk IM, and later, Google Voice with Hangouts.

This is a really bad move, yet again forcing Google+ down everyone's throats, when they've clearly said that they don't want to participate in it.
