That's a good analogy. I actually believe it is, at least for the near 
5-10 years.

Well, you're sharing that bw with everybody else on that splitter. Sounds 
to me that the service being delivered over that would instead be in the 
2-3 gigabit/s range for the individual subscriber (this is what I 
typically see on equivalent shared mediums, that the top speed individual 
subscriptions are will be in the 20-40% of max theoretical speed the 
entire solution can deliver).

As soon as one goes above 1GE, prices increases A LOT on everything 
involved. I doubt we'll see any 2.5G or higher speed equipment in wide use 
in home/SME in the next 5 years.

I am still waiting for a decently priced 10GE switch. I can get 1GE 
24port managed ones, fanless, for 100-200USD. As soon as I go 10GE, price 
jumps up a lot, and I get fans. The NICs aren't widely available, even 
though they're not the biggest problem. My in-house cabling can do 10GE, 
but I guess I'm an outlier.
