I've been using GV ever since its early GrandCentral days. I should highlight that the biggest hurdle was to pass the new number on to my contacts. Even then, when you call your contacts without going through GV's web-site, your contact sees your old/carrier number. The end result is a lot of confusion. On the other hand, I am now able to simultaneously forward calls (and now sms) to my VOIP (SIP) softphone and cellphone. The current exploitative state of the US cell phone market has made me hack my way through it using GV. So yes, "power users" can indeed get a big break from GV. However, GV may be moderately infinitesimal for people who blindly pay their phone bill without cursing.
