100mb/s is T3, or a slow OC.
personally don't see the big whoop about the faster connections really..
i have a 600kbit, and it downloads everything I need at a sufficient speed; plus I get pings of like 8-45ms gaming.
it's only when i decide to download stuff like Saga of Ryzom (trial was released few days back), where it's 1.3GB download; you kinda wish for a bit more speed. but still that much data in 8hrs is still not really long when you think about it.
what i don't get is how so many people can actually afford these ridiculously fast lines.. i mean 4mbit is the fastest here (only available in London) and it'll set you back £90/month.
my connection costs me £14/month; i mean that much cash per month seems stupid.
but then i guess i pays for itself when your Warezing everything in site
