I still can't believe Apple's pricing here - never even fathomed the idea of a cross-shop between the 2! So - upgrading from a 4S. LTE makes upgrading to *something* a no-brainer, IMHO. The 5S additions/upgrades over the 5/5C leave me a little wanting. Availability concerns also weigh in. Extra space would be a big plus for me, as I'm always hitting up against the 16GB limit on my 4S. Anyone facing similar?
