The service itself is good and very similar to Skype, with free calls to other Google Voice users and with some paid credits you can also make and receive phone calls to other phones. You can run the iPhone app in 2x mode but that is rarely preferable, making Google Voice a better choice for iPod touch users. Google Voice – Google Voice allows for very high quality VOIP calls, but unfortunately there isn’t a native iPad app.This is probably the best choice for iPad because it has a native app and is widely used.

And I think that since Apple introduced Facetime, companies like Skype don't want to do anything that seems like they are stepping on Apple's toes. But unfortunately, it has not happened yet.

Rumors have been running around about these companies finally supporting video chat for awhile, specially with MSN and Adium. You are waiting for Skype, (and MSN), to incorporate the software and codex to enable this feature. Basically, you are not waiting for the hardware to be able to support video chat.
