I was thinking about this and it is very expensive. And do I need 10G really? I do not think so. I did calculated few things when I was thinking about 10G and most probably I will not saturate 1G for few years.
And with phones ans laptops mostly WiFi is used anyways.
So can I ask you what is the advantage for using 10G equipment in your case? Even something really dull like network card costs around 100€.
