I just e-mailed a text message from my iPad to someone who does not accept iMessages. This made me think. Wouldn't it be nice if Apple created an iMessage-to-SMS gateway? I would prefer, of course, that a designated phone number, whether the device that uses that number is an iPhone or not, show up on the recipient's phone as the sender's phone number. I imagine this would make the iPhone look more favorable to someone who's stuck with a carrier that charges more for texting than for a good data plan. Maybe this would also make the iPod touch or iPad more favorable to those who do not, and may never, want to buy an iPhone. What are your thoughts?
