There are plenty of markets where LTE still isn't relevant. I'm in the UK, and there is one network offering LTE, at absurd prices.
Why should I pay more for hardware that I'll never use?
Much like the Galaxy Nexus, they can also release an LTE version later for the markets that want it.
Agreed.
I have a 4S, and I'm not due an upgrade until February 2014, but with Google driving prices down AND superior hardware I'm very tempted to jump to Android when my upgrade comes around. Or, sell the 4S and buy a Nexus 4 - probably making a tidy profit!
Going to test the Android water with a Nexus 7 though...
