Yes, The 56K dialup still exist and I think it will be existing for many years ahead cuz dialup is still a very easy source to connect to the internet (atleast here in pakistan). Many people don't know much about internet so they just install a modem and use dialup. They dont know much about cable net and DSL stuff.
Me too going to get a dialup line soon cuz my cable net (Ethernet) disturbs me alot.
I know, dialup will be slow but i will try to manage it
Its cheap if you pay by the minute (usually a penny a minute) and all you do is connect, download 20kb of data and disconnect. This would amount to about 1 pound (or 60 cents for you americans) a month. This is cheaper and far more practical than ANY broadband package.
Anything other than this and maybe instant messaging then id get broadband but it does have its use. Most people think they all use the web the same which is not the case as I have shown in my example
