While things might be moving now I still see 4G as a relevant technology years down the line, not now.
I can stream TV from my phone now and tethered pull down up to 5MBit/Sec. Why do I need 50Mbit/Sec on my mobile? I don't. I for one will not at all be jumping over to 4G as I see no tangible benefit over the existing network speeds available now.
4g is not just speed. It massively increases both network capacity and coverage.
Areas where you get no 3G should easily get 4g.
So when you factor that in, I'll jump on 4g due to coverage, 4g is also suitable for home broadband and in fact as part of teh license agreements to be auctioned end of next year, companies will have to legally offer home broadband on 4g, all part of the governments aim to get everyone, even those in the countryside on high speed Internet.
Not sure how this is affected by the different wavelength EE will be using.
