Just made a comment and it didn't post. Very disappointing.
It was in response to the comment about the 2x2 antenna design being a negative factor. As Tom and others know by now PC Mag.com just recently wrote a VERY critical article about this antenna situation and concluded that it was a black mark against the XR. The author Sascha Segan all but pounded a stake through the heart of the XR. I am hoping that someone will address this serious criticism and debunk it, if possible. I just bought a new XR ONE week ago and this will be in the back of my mind now.
This reviews is really amazing and so thorough. My compliments to Mark for his detail. Perhaps in the near future he will read Sascha's damning article and offer some rebuttal.
