I don't know why, but I feel compelled to comment on the *perceived* build quality issues of the Gnex. As a mechanical engineer I am a fairly critical person with regard to build quality, and in fact, whenever I review products (mostly on Amazon.com) I address the build quality (or lack of) of the items being reviewed. Having owned at least 5 different Motorola phones (and this being my first Samsung phone), I honestly can't see why people are critical of the Samsung build quality, unless maybe they're basing their opinions off of past experience with Samsung phones.
When I judge build quality, I look at things like:
-how well do the seams line up and are there large or inconsistent gaps between mating parts
-are there any squeaks or rattles when you shake or twist the product
-does the product *seem* sufficiently "hefty" for it's size and what it is/does
-do removable parts go back in place securely without a lot of fussing and are they securely held in place
-do moving parts move easily / smoothly or as intended or are they loose and wobbly
-are the materials used of sufficient strength for the products intended purpose
-etc
Having owned this phone for 3 full days and examining it critically, the only build quality flaw that I could find was a slight rattle coming from the volume rocker when the phone is shaken (not uncommon with many manufacturers). This is hardly a reason to declare that the phone is of sub-par build quality (in my opinion).
While I don't have any first hand experience with the Razr beyond holding a sample phone a the VZW store, and after owning motorola devices almost exclusively for the last 6 years or so, I can say that unless the build quality of the Razr is significantly better than previous Motorola phone models, then the Gnex is definitely on par. That's not to say that I feel that Motorola phones are of sub-standard build quality either, in fact I feel quite opposite.
In short, I really don't think build quality should be of concern to anyone who is on the fence about buying this phone.
