Realtek's $10 tiny 10GbE network adapter is coming to motherboards later this year

This is a most excellent place for technology news and articles.
Example of an ISP providing 10Gb/s in Portugal here and at 15 euros a month it's pretty cheap too.
That same ISP is from Romania and is also in Spain though curiously in this latter their Net Only 10Gb/s subscription costs €25 per month,
Personally I don't see the point of it for myself at home, but for a small business I can see it making sense.
