If Apple released iMessage for Android my Apple device iMessage experience would be far better.
You can bet your bottom dollar any Android user at all clued in would install iMessage. A situation which would allow me to use iMessage exclusively. As it is now I'm juggling about 5 different chat/messaging apps. It's a mess. If Apple is really all about the experience they need to do this. I'm sick of the current situation.
And I don't at all buy the argument that this would result in the sale of less iPhones for Apple because Android users wound't need to buy an Apple product to get access to iMessage, thus forcing Apple's hand. That's a fallacy.
