I'm on broadband. My 70 y/o Mom actually got it before I did! Boy was I pissed!
Out of my 3 brothers and sister:
One brother has it.
One brother is very wealthy, and the homes are spread so far apart in his area, cable and DSL aren't available there yet so he's using ISDN now. He's building a new house in the same estates and just decided to have a T1 line installed instead of waiting for DSL or cable any longer.
And another brother doesn't have it. He's mentally disabled. He uses a free dialup service.
My sister hasn't gotten it yet, I keep asker her why, because her daughters are in a private college prep high school and spend a lot of time online for research.
Some of my friends have it, some don't. The ones who don't have it are newbies, or can't get it.
