As stated before, the tablets allow you to make voice calls 3 ways...

1. Google Talk
2. Skype
3. Gizmo

Google Talk on the tablets let you voice chat with other Google Talk tablet users (also has video capability). With the coming 2008OS there may be other abilities with Google Talk.

Skype on the tablets lets you voice chat with other Skype users for free. You can also call "land lines" (regular telephone lines) for a price by buying "Skype Out" credits.

Gizmo on the tablets allows you to voice chat with other Gizmo users for free and with the coming 2008OS video chats will be possible. Gizmo also allows you to call "land lines" for a price with "Call Out" credits... at about 2¢ per minute (within the U.S. and Canada).
