<span>The short story: you’ll need just a computer and to have downloaded Skype and an internet connection (broadband preferred).
All modern home computers can run Skype and you can use the built-in microphone and speakers to make calls. You’ll get much better audio quality if you buy a headset. You can purchase one at the Skype shop or at your local computer store.
The technical bit: You need a PC running Windows, a sound card, microphone (built-in or external) and speakers or headset.

Andersp: You need a PC running Windows
Everything you said is correct except for that part - Skype is available for other platforms as well - including Mac OSX, Linux (but the Linux version is always way behind), Windows Mobile, Smart Phone, Nokia N800/N810 and WiFi phones with integrated Skype and standard cordless phones with integrated Skype. So WebTV users that don't want to buy a PC could as well buy a phone to use Skype. In some countries there is also a Skype phone available, called "3 Skype phone".
EDIT: On this Skype download page: Download Skype for Windows you can see a rather complete list of links with further information on all the platforms that Skype supports on the right hand side.
