Cheap phone calls?

As an example of up-and-coming technologies SKYPE is very promising, with the ability to extend IP telephony to the desktop.

PC to PC phone calls are free, and their PC to landlines calls are comparatively cheap.

Although it is best with broadband and a fairly decent PC (>1 Ghz) SKYPE is usable even on dial-up or lower end machines (500 Mhz Celerons).

The inclusion of multi platform software is very shrewd.
