Yes, they will...
They will buy it just because it's an iPhone. When our contract was up back in June we upgraded to smartphones. My wife opted to shell out $150 for the 4S just because that's what all her friends told her she should get. I settled on $25 for a Motorola droid. My phone does everything hers does and more (except talk back to me) and does it faster. It has a slightly bigger screen. It takes better pictures. It has a better GPS. The sound quality is better. etc. I find the iPhone frustrating to use because it only has 1 button so navigation is tricky at best. I just don't see what the big draw is for an iPhone.
