"while google in the US is rolling out gigabit, and the private sector in UK is doing the same...."
Google are not "rolling out gigabit". Google have realistically done nothing more than a very small-scale trial. Add together the population of everywhere Google Fiber covers or has promised to cover -- that's Kansas City, Austin, Provo, and one neighborhood in Palo Alto -- and make the erroneous assumption that every resident is covered, and you still have a "rollout" that touches only 3.3 million people in a nation of 313.9 million.
That's one percent of the population if you make an erroneous assumption, and far less than one percent in actual fact. More than 99% of the population has no access to Google Fiber, and is unlikely to have access to it in the next decade.
In fact, the vast majority of the US would *love* to have access to anything near 100mbps, because that, for most of us, would be a HUGE upgrade from what we have now. And even if it is available, it's typically accompanied by a ridiculous pricetag.
I'm in the 64th-largest metropolitan statistical area in the US, and I'm lucky to have 100mbps internet available to me -- but it's priced at US$115 per month (AU$127/month) BEFORE equipment charges, fees, taxes, etc. And that price tag also assumes I am paying at least another US$20 (AU$22) per month plus equipment charges, fees, and taxes for TV service, whether I want it or not. Last time I checked, the penalty for not having the TV service was higher than the cost of the TV service.
So realistically, just getting 100mbps internet in the US will set you back US$150 (AU$165) per month, if it's even available to you -- and chances are, it isn't. Gigabit in the US? It's a pipe dream for almost all of us.
