I've tried having Siri text different numbers that only have a phone number as mobile not iPhone, but Siri still sends them as iMessages. Is this by a "feature" to get me to bug my friends into getting iOS devices, or am I missing something?
I don't know what to tell you. After reading your latest reply, I grabbed my iPhone 4S, and used SIRI to send my oldest son who has an Android device a text message stating, "Good morning", and it worked without a hitch. I'm sure you have already, but go to Settings-Messages and then scroll down and verify that "Send as SMS' is turned ON. Do the same for "MMS Messaging", if applicable. Also, try signing out and then signing back in to iMessage.I know that, what I mean is Siri sends as an iMessage to my non-iPhone friends. Checking "Contacts", they're there as mobile, not iPhone. But Siri still sends as iMessage, then I get the exclamation mark notification on Messages.

Didn't mean to come off badly. I feel stupid, forgot to turn send as SMS back on after going to iOS 6.1.2 (did setup as new).
Also Messages regardless of whether Siri sends them or you do it manually doesn't care what you have the contact's phone number tagged as in your Address Book. Apple maintains some sort if database to tell Messages whether to use an iMessage or SMS.
Like any data it can sometimes be wrong especially if someone used to have an iOS device and switched their phone number to Android without turning iMessages off.
