Andersp: I already have it, I was asking on behalf of a couple of webtv users from another site. Thanks.

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.

Gordon Shumway:  Everything i said was c/p from Skype's FAQs...the point is that a computer is needed.

I'm using Skype very often, use to have long video talks with friends in Sweden.  Dont think its as fun using a Skype phone tho :)
