"If your on a 2 year upgrade plan you have to remember the vast majority of people that are eligible for the 5s are still using a 4s. Think of the differences between those two rather than the five to the s..."
I am thinking of those people. If you are now eligible to go from a 4S to a 5S I think you should really take a second to evaluate. Apple will almost certainly make changes for the Iphone 6. If you upgrade now, from the 4S, you will have a year to wait until you can get the 6. If the 5 wasn't enough to get you to upgrade, the 5S surely isn't either. Not to mention, I honestly cant imagine it will take Apple another year to release the 6.
