Not really an "inside view" as the Nexus Two, or Nexus S has been leaked all over the place. It is rumored to be a new version of their Galaxy lineup, curved back, dual core processor, 8MP camera.
Not a bad device, but not that much more than is on offer on a G2 or MyTouch 4G.
As for the Nexus One - it really did not turn out "poorly" for Google - they sold out of all the inventory, and was/is a very desirable device.
