On HSPA+ (H+) my connection is fast enough for any purpose besides downloading movies, and it's not like I've got unlimited data. Even 3g's theoretical speed is great if they could get that to work for a change.
I have 4g on a company laptop and the speed is better than many places' WiFi, but I have yet to find an excuse to use it (someone has to pay that data bill). It's not like I don't know how fast it really is, I just don't see the point of it right now. In 5 years 3g really will be too slow for many applications, but as it stands...
You answered your own question. It's progress, and the sooner people around the world adopt 4G, the sooner it becomes the standard, just like 3G before it.
But in 5 years, in all reasonableness, you'd have a new phone. Having no lte on this one doesn't change much. That's what I meant to say.
It contends better too, which affects everyone.
I have unlimited LTE for £15/mo (Three UK) so I don't need to worry about paying for the data.
additionally contention levels are just horrible on the 3g services. what's that 20 Kb/s and 40% packet loss just because you were silly enough to use it near a train station.
