call other Skype users
anywhere in the world and talk
to them for free. You can even
talk to each other live over
video.

Skype
The one problem with Skype and other first
VOIP services was that you couldn't get a
local number. For example, Skype doesn't
offer a Skype In number in your state. This
means that if anyone calls you, they'll have
to pay long distance charges. That's not very
attractive.
