Lumia 920 Owners

I don't own the Lumia 920 but I am interested in it. However i am concerned at the number of technical problems that users seem to be experiencing with the handset such as constant reboots, poor battery life, overheating, dust in front facing camera......even after the Portico update

Now, I know that technical support forums do tend to attract technical complaints and frustrations from customers rather than people taking the time to give the handset praise so i am wondering if i have been sampling a strongly negatively biased view on the handset...

So i ask you, is the Lumia 920 a dudd?
