I got mine yesterday! Works great, but has a few bugs that need ironing out. There is no delay or callback - just dial direct and the called phone rings right away, but overnight the service conked out and I had to power cycle the unit. Won't receive incoming calls if you are logged into Google Chat online. Takes 2 to 3 minutes from power up for the GV service to become active. Voice quality is excellent. GV has no 911 service, so have another means to place emergency calls.
