4G is widely available in cities like London where I am currently living. A large amount of friends use 4G in devices like the Z10 etc without having serious deterioration of their battery life etc. The difference in data speeds is simply huge.

4G support is something that can really add value not in terms of silly spec-wars arguments but most importantly in terms of user experience. I think it is also making the phone a bit more future proof and along with an optimized OS it should make the "smartphone" experience even more smooth and intuitive.

I don't mind waiting a bit for 4G support to be enabled but since the 4G support has been announced from day 1, I think most of the people would like it sooner rather than later, as something that the phone supports "out of the box".
