Between this, the unlocked/contact free prices for the Nexus 4 and google maps? I'm typically an iOS guy and I'm right with you. If only they had put LTE in the Nexus 4!
Until then, LTE is for those who have to have the latest thing, regardless of price or who actually need the data rates achievable with LTE and have coverage where you're likely to be using it.
Um, no. There's a mountain of difference between HSPA+ and LTE. The former is like having medium-speed cable Internet, and the latter is like having FIOS. This has a direct impact on user experience.
