Speed matters less with each step up. Going from a modem to broadband is amazing, going from something like 256k DSL to 20mb cable is pretty damn huge, however going from 20mbps cable to 200mbps cable is nice, but fairly minor and going from a few hundred mbps to gbps is hardly noticeable.
I have 150mbps cable at home, and get what I pay for. Games from GOG and Steam download at 18-19MB/sec. It is fun, I can download a new game in minutes... however outside that I notice little difference from the 30mbps connection I stepped up from. Streaming worked just as well before, web surfing was just as fast, etc. The extra speed matters little to none in day to day operations.
Same thing at work. I'm on a campus and we have some pretty hardcore bandwidth, as campuses often do, so much it is hard to test as the testing site usually is the limit. Downloading large stuff it is nice, though really not that much less time than at home. I don't really mind the difference between a 2-5 minute wait and a 15-20 minute wait for a program. Surfing, streaming, etc all are 100% the same, no difference at all, speed seems to be limited by waiting for all the DHTML crap on a site to render, not the data to download.
While geeks get all over excited about bigger better more when it comes to bandwidth, for normal use what matters is just to have "enough" and "enough" turns out to be not all that much. It'll grow with time, of course, higher rez streaming, larger programs, etc will demand more bandwidth but still this idea that there is the difference between uber fast Internet and just regular fast Internet is silly.
It will not create any meaningful divide.
