You are 100% correct. I had been waiting for months for the GN. I was frustrated when it was delayed, and I had mine the morning they were available. I have no problem rooting, hacking, or with instability.
However, I think you are missing my point. If you walked into the Verizon store as a newb, what phone would you buy? There are only a few that make sense: Iphone, Galaxy Nexus, Razor Maxx....Rezound??? hmmm. Honestly, which would you buy if you were not a techie?
Since Verizon expects to add 300,000+ subscribers a month, and at least 50% are buying smart phones, there are 100,000+ GN being shipped per month.
So the idea that the GN is a phone targeted at only the most technical savy is not correct.
My frustration is that I still do not have any official updates for my "Developer" phone to address long known issues, or add enhancements that I expect as a "Nexus" user. To make matters worse, I don't have simple things like a desktop dock, and Multi-media interface that were promised when I bought the device.
In my opinion, unless Samsung/Google do something soon to dramatically improve the usability/stability of the GN and Android in general, Iphone is going to begin taking market share by appealing to users who just want their phone to work!
