When it comes down to having the best of the best, some people have asked me why it's worth it. Bottom line... over the course of a year or two, I'm shelling out $1.5 a day or $0.07 an hour for something that I'm on ALL THE TIME! Does that make it worth it... yes! The fact of the matter is that I might end up paying another $400 once I sell my iPhone 5 64GB in White for AT&T, but as the number one tool in your pocket? It's dumb to have a "free" iPhone 4S which is two years old and keep it for another two years. Also, if the iPhone 5c is nothing more that a .1 update to the iPhone 5, it's not worth it. The camera, and Touch ID alone along with the A7 64-bit processor, I'm expecting nothing but awesome with the new iPhone 5s. This also puts me in line with Brian Lam of The Wirecutter on the new iPhone 5s. I asked him a while back on the iPhone 5 and he responded to me via twitter with good points. He also recently wrote this on his website too.

I’m just saying you should upgrade because a few hundred bucks is not really a lot of money for something if you use it all the time, every day, and are already paying a hundred bucks and change a month in service fees over several years.

I'm going to find out what I can fetch for my iPhone 5. Any offers? Gazelle is up to ~~$360~~ $340 buy I wonder if I could get $450 on Craigslist? It's still jailbroken too by the way running iOS 6.0.2.

update: Lifehacker also talks about future proofing for only $100.

Considering the price difference between the two models is only $100, your best bet if you have the cash is the iPhone 5s for future proofing, which is worth it considering since you'll have to sign a new two year contract to get the discounted pricing.
