I'm not touching EE. If they were priced the same as 3G, I probably would, but I'm just straight up not paying any premium whatsoever for it.
Here's why: At home I have Wifi. At the office in London I have Wifi. Between the two I'm on trains. On the underground, no signal what so ever. On the overground into and out of London, theres a tunnel every 10 minutes so the signal is somewhat sporadic. If I'm traveling out to see clients and such it's a crap shoot if there is 4G there anyway.
I just can't think of any useful way to use 4G under those constraints.
In a few years when 4G is more universal and the costs come down some, then sure, why not I guess. But in my present lifestyle I can't see any real benefit. What are you people doing with your devices that demands the extra speed? I wanna download something substantial then I can step into a starbucks and grab it, or just live with it taking a minute instead of 30 seconds. As for mobile video... even setting aside that video streaming will dissolve battery life, you can stream pretty well on 3G anyway, not perfectly but well enough for it to not be an issue. I can't think of a situation where you'd be stuck somewhere with no Wifi but also rocking 4G coverage and that you'd want to just start streaming TV shows. Personally, I carry my TV shows with me.
Also, data caps people... Even assuming a situation does come up where you could make use of all that speed, you are going to be either running against the cap pretty fast, or paying a LOT of money. If you going to stream you'll need over 1Gb, but anything over that will cost a LOT more than any competing network. Even their 1Gb plans are 10% over the competition, and that adds up. The 3gb plans are about 20% over the competition, and then beyond that you're getting silly. An 8gb plan is FIFTY SIX QUID.
So how much are you really going to use that speed? It better be a LOT.
