IMHO The Nexus 6 is the single most significant smartphone of our time, in its size class. This is a world class product created by Google and Motorola's finest.
All products are comprised of a series of compromises caused by the multitude of considerations and limitations. This Nexus is the result of these two companies working very diligently to create a truly outstanding finished product. I have no problem with that statement even before the reviews are in.
I predict the Nexus 6 will receive excellent reviews and quite possibly rival the Note 4 in sales volume.
Perhaps I'm completely wrong... Time will tell
