Is it worth burning the upgrade to move from the 5 to the 5s? Or wait another year and just enjoy iOS7 on the 5?
For the first time, I actually bought the AppleCare+ on my current 64 GB iPhone 5 so I was thinking of maybe skipping the 5s (though, I'm a tech crack whore and have always upgraded previously).
If you don't have a 2-year upgrade available then I would stick with the 5.
If you wanted to sell your 5 via craigslist and upgrade for full retail price then you would have to figure out if it's worth the $200-400 it will cost.
You already know the benefits of the 5s so you also know the costs vs benefits.
Now decide.
