I do, but like most I'm more lead by logic and sensible explanation. I haven't yet been convinced of the need or benefit of 150Mb/s speeds on a 5" mobile device on a capped 20GB plan, over and above more sensible speeds that are perfectly good for virtually any task and may come with a more relaxed usage restriction.

Just why are some users obsessed with that dial moving around as far as it can go? I get it for testing, but in the real world I don't see the need. It seems to be a 'mines bigger than yours' need more than anything.

I'd be the 1st to criticise speeds that impact the day to day things users want to do like browse or stream, but once you get 6, 7 10 Mb/s then the benefits diminish, 20 30 40 60 100, 150 I think ... and the point is....? on unlimited at home fine, but it is capped, to 30 minutes usage at those speeds.

Why don't you go gain some knowledge about how high speeds can be good and then try again, you can start on the previous page with the posts just after the first time you decided to drop your unfounded opinion into a post,

Jon's post is probably a good start.

PS
As has already been said, it's got f-all to do with speed tests...

I think the point others are trying to make is that just because something is delivered more quickly on a very fast connection (eg. a 50Mb file or a 500Mb film download) doesn't mean that any more data is being consumed. It's still a 50 or 500Mb download, however quickly it arrives on your device. If you need or want that file immediately, you would still download it and use the same amount of data however quickly or slowly it was delivered.

Therefore, for this example the advantages of having a very fast connection might be less battery drain and less time to wait for the file you need.

I agree that if you wanted to stream something 'live' and could get the same quality, without buffering, at 10Mbs that you would get at 100Mbs, there would be no real advantage. However, there would also be no detrimental effect on data use through having a faster connection as the amount of data you were transferring would be no different, so it wouldn't use up any more of your allowance. Any data cap would be no more limiting on a fast connection than it would be on a slower one.

Ultimately, I think that the potential advantages of very fast connection speeds will depend on how you use your device, and what for. Maybe for your use cases, there will be no advantage to having a speed of over 10Mbs, but if your connection was quicker and your usage stayed the same, you would not see any greater data consumption either.
