As frustrating as the delay is, I'd much rather they get everything right with the phone before rolling it out. My wife got a blackberry storm 3 years ago shortly after it released and the thing was so buggy it was absolutely unbelievable. I couldn't believe RIM/Verizon would release something in such an almost unusable state. After our experience with that phone, I knew RIM was in big trouble and haven't been surprised at all with their recent fate.
So after that experience, I would much rather Verizon/Google/Samsung/whoever get it right with the phone before release. As others have mentioned, it really sucks to be stuck for 2 years with a phone that has major hardware or software issues.
