I personally opted for this plan because I have a 50MBit landline at home and most of the time use my WLAN at home or at work. No benefit in using mobile data. I barely ever go over my limit - but next week I will be off, so I guess this will be the first time I get throttled from my 21 MBbit/s speed.
First of all - the benefit - as we both know, currently voice over LTE is not possible. Therefore it would be a godsent for the battery, if the LTE-radio part would switch on, do all the syncing in about 2-3 seconds and then switch off again. Same applies for webpage browsing: Switch on - load the full page in a second - switch off.
Second - the ICE example. Who gives a flying **** about this stupid example. Why should I cut into my personal data amount, when there is a free WLAN Hotspot in that train?
Being on a train in the Ruhrgebiet nevertheless won't be any problem, as there is about 75% coverage. You simply don't grasp the concept of a roll-out. Same thing in the last discussion with you. The rollout happens, and it happens at incredible pace. I currently don't use LTE in a phone as I wanted the Galaxy S3 and didn't want to wait for the LTE variant - nevertheless it was a tough decision not to get the HTC One XL.
But you are just like the people, samcraig characterized earlier. If the iPhone5 won't offer LTE it's not a big deal as no one uses it in your world - and if it is rolled out with LTE then it is the "pioneer of a new technology" and the best since sliced bread.
Too predictable - sorry.
