Woah - I know many don't have fibre/cable, but I thought at least ~20Mbit speeds were the majority.
Where are you may I ask? Is that common where you live? Is it costly?
Actually 20Mbit/s is a lot even in germany...
More likely to see 6 Mbit-16Mbit while some cities have 25/50/100 but if you are living outside of bigger cities (which most people do) you will end up between 6 Mbit-16Mbit and some area's are worse.
Very common in "rural" UK, where rural means 5 miles away from a city. You'd expect to pay £20-25 per month for the privilege (although note that this includes a "line rental" charge paid to the layer 1 provider - BT - of approx £15 per month)
