The only reason I consider getting an iPhone is for iMessage. I would gladly pay a monthly fee so I could use the phone I want AND communicate freely with the people in my social circles.
$10/month and you get your iMessage on Android.
How do they make money doing this?
I would be willing to pay $10 if the solution wasn't so hacky... Maintaining a system solely to run unsupported software (in a way that I would have to imagine is against ToS somewhere) is just too risky to handle a critical piece of my communication. I can't drop a message - especially if my excuse for dropping messages is "the laptop in the corner of my closet had to install a security update and restarted on me"
