This.
At least one other guy got the phone. (the one BB called to get him to return it)
Is he having the same issues I wonder. if not, the chances of you having a dud are higher. With only a handful in the wild, the chances are very low that one would be a dud, but the chance is still there. Sometimes you do just get dealt a straight flush, or in your case, a pair of 2s.
I will say that I have not noticed any real issues. Now, I'll admit I don't have the best memory in the world, but I can't think of anything I've come across in ICS or the Nexus that has made me think, "Oh, so THAT"S why it's not released yet." I'm not saying there haven't been any bugs or issues, but honestly I can't think of anything right now off the top of my head.
The speaker: I noticed on pandora when playing music, I had to get the volume up to about half way in order to get the sound output to the same level as about 1/4-1/3 volume on my iPhone 4. I had also missed some texts, but then after changing my text notification, I haven't had any issues. Speakerphone volume was very good; it was on par with iPhone 4, I'd say.
And yeah, not having the ability to switch to 3g is kind of a pain. But I'm sure when ROMs start coming out, then it's a moot point.
Almost forgot to mention: I haven't had any issues with service/LTE. I live in Atlanta, however, so I guess living out further away from a city might affect it. (I've been able to get ~32mbps over LTE)
And I'm guessing the stock battery will last you a day at least. I know from my experience that in my first few days of owning a phone, my battery life can be cut in about half due to playing with it constantly. Yesterday I was able to take it off the charger a little before noon, I think, and I just put it on the charger a few minutes ago.
I don't want to turn this into a review post, but I will end with saying this phone is very impressive. Not just from a hardware standpoint, but from the software side, too. This feels like the first time that Android has felt like a true competitor for iOS. It really feels like night and day between 2.x and 4.
tl;dr: Trust the professional reviews you've been reading. This IS the best Android phone available right now (whenever it comes out). OP isn't necessarily wrong, but he might have got a lemon or is just overly critical trying to stir up some noise.
