I took the Gtalk update today, got the red font update failure on startup, and everything worked fine after that.

Just made a 45 to about 1 hour video call from a better 3G spot and this time both of us could see each other. It worked great, at least compared to skype or vtok on my iphone 4s. from the same spot those iphone apps were freezing up instantly. I didn't get any video freeze on the n9 until i started multitasking to take a screenshot, but that resolved in a minute or two.

the n9 multitasking worked really well here. when i minimized the video call, it was still live and i could see my contact still moving in the minimized screen, and the call audio was ongoing. that was pretty awesome, but I guess to be expected from maemo/harmattan. I scrolled over to the apps and opened screenshotme and was able to open that to take a screenshot of the call and all of this happened smoothly without interrupting the call (except the one-time brief freeze, but another time the same steps did not freeze, so it could have been a network fluke).

I'd say 45 mins to 1 hour used about 1 GB of data, according to my n9 data counter. the video quality is decent and smooth for both ends, not laggy. when I switched between front and back camera my contact said they didn't notice a huge difference. all of this call was with the less powerful front camera.

I'm quite happy with this feature. I'm very surprised i had a better experience with it than the iphone skype/vtok apps.
