Isn't this only a problem if one of your devices trying to access these messages is a non-apple device?

For a while I was switching between an iPhone and Android (I was deving on both platforms and so would switch them out regularly).

Then I found out the Apple would think I was still using the iPhone, and would therefore would send my messages via iMessage, and I'd have no idea I wasn't getting them.

But what incentive does Apple have to change this? And realistically, how many people does it impact.

Do most apple people know that iMessage isn't using SMS? I think they just look at it as an app that sends messages to everyone.
