That said, I ran a internet radio station + free image host node on my residential connection and was pushing a few TB/mo up and never got any complaints. And BitTorrent is obviously quite popular in Sweden so I'm sure there's a bunch of seeding going on.
But true, while 100/100 Mbit is commonly an option in big cities (when I looked for an apartment in Malmö a few years ago, all the ones I looked at had 100M-1Gbit), I'm sure most people go for the cheaper 100/10 option, since most people aren't uploading anything. One friend has 250/50, which seems like a good compromise.
Also I noticed there are very rare use cases when I'm able to actually get over ~30Mbit or so downstream, usually the servers I'm downloading from aren't capable of delivering data so fast.
Smaller cities usually have decent connections over DSL or Cable though, so bandwidth is usually not a problem anywhere you go in this country.
