I think this is a pretty good sign. Outside of the volume issue, which is already fixed, all of the other complaints people have are purely opinion based.
Cheap Build? Thats just personal preference. I got a chance to mess with the nexus today, felt fine to me.
Bad Camera? Again, opinion. Is it the best camera in the world? No, but honestly I'm not trying to become a professional photographer with my cell phone. The pictures look plenty good to me for everyday use. Not to mention facebook and every other website is just going to compress the crap out of the pictures anyway.
Slower transition effect? Again, opinion. Personally, it annoys the crap out of me when my d3 is flipping from landscape to portrait with the slightest tilt. This is even worse when I try setting it down on my desk. The 2-3 second delay experienced on the nexus wasn't even enough for me to notice. I only knew it was an issue after I came on the boards and saw people complaining about it.
People have different opinions. If whatever your cell phone experience is is seriously dampened by an addition second or 2 wait, thats totally cool. Just wait for that phone that has instantaneous transitions. But frankly, if the worse thing someone can tell me about the phone I'm going to buy is that it isn't a DSLR and it takes an extra second to switch into landscape, I think I'm in pretty good shape. Makes me feel confident in my purchase.
