Busting your data allowance in minutes
While I agree with the general gist of this article, I can't stand the continued trolling of the old "but with 4G you'd use your data allowance within minutes!" line - what is it with this assumption that on 3G you use data when you have to, bit by bit, but as soon as you have a 4G connection, whoa, I'm gonna go off and download the whole internet to my handset in minutes...
Erm, no. Sure, if the extra speed (but let's face it, it's not revolutionary speeds compared to what the best 3G connections can manage) means you want to start running bittorrent over your mobile connection, or downloading Linux distributions to your handset, then you're gonna have the same problem you did on 3G, you'll just hit those problems just quicker.
The point of 4G (and I'm not a massive fan, having just signed up to another 18 month 3G plan, but I'd have it for free, thanks) is that you can do what you did before, but quicker. You use a gig or two a month currently? You'll use a gig or two on 4G, maybe a touch more because you can work quicker, but everything will happen quicker*.
* Supposedly it'll happen quicker, though I maintain for most things we do on mobiles/tablets, will we really notice that 0.2 second page load improvement?
