I have to admit, if I had the choice of an iPhone 5 and a 4S at a big discount, I don't see a good reason to go with an iPhone 5....it makes little sense for me, since on a phone, LTE is just not something I need to pay money for and the screen is only slighter larger. Yeah, the iPhone 5 is faster and has a more powerful processor, but the 4S doesn't feel slow to me at all. I can see why many are making this decision. Come October, I will be able to buy a new phone. At this point, the desire to have something new seems like the main reason to upgrade.
