I'll go first - what's the point of LTE?
I mean I know from the operators point of view - it's a more more elegant and efficient system - but does anybody actually need this much bandwidth on their phone?
3G does me just fine for my mail, spotify and the odd bit of video streaming (and for this I'm usually using wifi) - what service do we have that actually requires LTE?
And, if this service did exist, it would be so massively expensive due to the operators retaining their old charges.
I can see it being extremely useful to provide pockets of 'internet' to homes in areas without cable/decent quality copper, but that's about it.
