Yeah, we absolutely don't need that kind of bandwidth right now, but it's nice to be future proofed. Plus it's only about €30 a month, including all the extras (telephone, internet, hard drive, wifi, TV, all networked etc.) In full disclosure, we are actually a showcase building for FREE, (one of the main internet companies here in France) as our apartment building's owner is an ex satellite installation guy and begged them for it as he's a long term customer who knows what he's talking about. :) Not sure of all the technical details, but each apartment has it's own separate 1GB fibre line, not shared amongst the whole building etc. Do count ourselves lucky, but what to do with all that bandwidth? Like I said earlier, we are waiting for the rest of the internet to catch up and rarely get anything near our max speeds, at least on download.
Having said all this, I have techy friends in Japan with even faster internet. :)
