You're missing the point entirely. No one is talking about removing icloud or email accounts or restoring phones... this is about SMS, a feature that has always followed your number since the beginning. That is of course until iMessage came along. The sheer fact that some customers have difficulties with technology should be reason enough to make this as dead simple as possible... something that Apple has always touted as their reason for being. And just because they might not be as savvy as you or I doesn't negate their right to own these devices. In fact, the ones demanding more technology are probably the ones who didn't have any problems with iMessage and switching... those who don't quite understand it probably aren't asking for anything more than they currently have, yet are victims of the tech everyone else is screaming for and perhaps their peers or family members are pushing on them. How many non-tech-savvy individuals out there have upgraded to smartphones simply so they can video chat with their relatives (for an example)?
I think it's rather harsh for these people to be called ignorant while at the same time being pressured into keeping up.
But back to the point... SMS is SMS is SMS... it should always follow your number, plain and simple. Apple should never have been allowed to intercept this, or however it works.
