The camera is really the only selling point. Most phones nowadays are fast enough to do anything you need.. When we get home she pretty much drops the phone for her iPad anyways.
Then it's probably not necessary to upgrade anyways if there's nothing wrong with her phone. The 4S still performs pretty well, IMO.
You should do what I do with my wife's line and stagger your upgrade cycles. That way, each year, you have a line up for upgrade and can pass your phone down. If she doesn't really care about upgrading her phone, just hold off until you want to upgrade next year and then pass it down. Works out pretty well for us geeks .
Does anyone know if the 5S or 5C will support voice and data at the same time on Verizon? I use my Nokia 822 as my main internet (and phone) at the house through the internet sharing feature since I have unlimited data. My friend with a 5 says he can't do that because it doesn't have all the required antennas. That was a deal breaker for me. I have to say that after using WP8 for the past few months, I wouldn't be interested in an iPhone unless it has some really important new features and can surf and talk at the same time.
I'm going to go out on a limb here (because we don't know) and say that the iPhone 5S and 5C will not do Voice and Data at the same time.
It's not that it doesn't have the proper amount of antennas to do so, it's that Apple has decided to prioritize the antennas for voice over data to automatically improve call quality if one of the antennas is faltering. Honestly, I think two antennas for voice are perfectly sufficient and the three Apple decides to use is just, quite simply, overkill.
The only reason I say that is because I don't recall any talk about an improved antenna system. It seems, on the surface, as the 5S and 5C will share the same antenna system as the 5.
One of the biggest things I'm looking forward to, honestly, is the near-universal compatibility of the Verizon iPhone 5S. It basically covers everything here in the states and I'm thinking I'll finally be able to order a iPhone 5S off my works Verizon account, pop my AT&T SIM in it and get full service with LTE and everything. Can't wait until I get the first one in here just to check it out.
