Buffalo, a Japanese Gadgets company, have released these wonderful Skype Keyboards which have a built-in headset or the Skype Phone.
The keyboards connect to the regular USB port of the computer using just one cable so you save the wiring hassles of connecting a separate Skype phone.
You can even use it as a speakerphone to keep typing while making phone calls.
Logitech has a similar product - Logitech Easycall desktop - for making Internet phone calls though it comes with a stereo headphones with mic set and the keyboard provides one click access to launching IM programs or managing voice calls.
