With all the Google XMPP demise talk, I switched as well. I got the two year plan and I must say, I am happy as well. I was previously paying Anveo for 911 service so with the switch to Vestalink, I get 911, full caller id info and a bunch of other options which I wasn't getting before. I still haven't ported my number over to Vestalink and may just leave it with Google for now, but may eventually port it over. Since Google Voice is getting so little attention from Google, there may come a day when it is no longer around. Also, setting it up via the Obi portal wasn't hard at all.
