I have tried dial-up before on some Linux installations and found it to be horriblly hard to get working.
I've not tried dial-up under Ubuntu (not having any dial-up service to access). How easy is it to use?
I ask this because at home I have a PC with a 2GHZ CPU and 384 MB of RAM. While this works well under XP with SP2, it will probably be horribly slow with XP SP3. As my elderly parents will be using the PC I need something very simple for them to use, which won't need a ton of explanations over the phone.
