I've used GV with my iPhone 4, HTC EVO 4G and HTC Hero. Also with SkypeIn/Out numbers. Mirrors my experience, especially on iPhone: freezes often, messages can be delayed, unreliable voice service, voicemail transcription is rarely accurate. As soon as there is a problem and I have to switch to my carrier number, and confusion exists again. I also run into the problem stcredzero describes; showing up as "Unknown", forcing me to move back to carrier number. In short the biggest benefit I get from GV is actually the Chrome extension where I can send SMS messages very quickly and play voicemails (the transcription is usually useless) - really wish Apple would acknowledge that tying your phone to a browser is really powerful. I've switched to giving out my GV number professionally and using my carrier number for close friends and family. That vanity number is just not worth it. Disclaimer: I am not an idiot and I understand how GV works.
