gerbick: I totally get your point. Anything that is said now regarding antenna, bluetooth, call quality, etc. is only preliminary. I did read that someone used it with the car's bluetooth and it worked fine, same with Nokia 360. It is very early stages, but it is a beginning.

I already ordered my phone, but I was looking for something different: massive red flags, this is why I ask to compare it with another phone. I know my N9, I know my 5800, I am aware of a few others (e.g., Nexus 5 doesn't match N9's reception in the same low reception area, nor does it match the iPhone 4's).

Again, these aren't thorough tests, but they give you an idea. In my experience the N9 failed with a bluetooth headset (or earset maybe, not sure how to qualify it) the minute I used it. The fact that somebody else was successful the very first time tells me that there is a possibility that it's better, which works for me :-)

EDIT: since I'm here, it was also mentioned that WLAN was quite good, at least better than an Android tablet (but that's easy...). N9's is a bit poor, at least in comparison with a Nokia 5800.
