I have anything faster than a Dial-up. The one I have is a wireless broadband, and that falls in the high speed category.
I remember having Dial-up back in 2000. It was sooo slow... At least I'm satisfied with what I have now, but dial up never satisfied me and only left me with annoyance and pain.
Dial-up also doesn't let you use a lot of services and a lot of features that broadband high speed internet lets you use, so it's sad to me if some people are still forced to use Dial-up in order to have internet connection, specially for the costs.
I advice everyone to upgrade to the high speed broadband or better if they can afford it with ease, since that would make the whole internet a little bit better.
