Even though many have fast net connections these days, many such as myself have to rely on dial-up. It would be great if there was a tutorial or too on dial-up for mint as it took me a few weeks as a new user to get online with the communities help.
In the end I settled for a USR 5637 USB modem, which works out-of-the-box without the need to install drivers. Although that said it took me a while to track down in the Ubuntu forums that you have to remove the "modem manager" packages as it conflicts with USB modems.
With this in mind, I also think it would be good to have Gnome PPP dial installed with mint by default for those that can't get online without it.
