I'd be surprised of most people chose cable over fiber - everyone I know choses to download TV after it airs in America instead of paying comhem 500 kr/mo for shows that are 2 years out of date.
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.
