Well I can't speak for ID, but I also claim this phone to currently be the best available on the market and:
I have owned a myriad of smartphones to date (various models of the iPhone, several Samsung and Sony droid devices, and windows-mobile devices of the past) and....
I also forgot to add the several Blackberry devices I owned/used in tandem with some of these other devices (mostly while I was on droid devices) because nothing on droid even came close filling my business/enterprise-integration needs at the time.
This is not to say that I don't have some issues with it. For instance I don't like how it appears to be impossible to connect the Lumia to an adHoc WiFi network using static addressing at this point (the phone has no trouble connecting to regular WiFi networks also using static addressing). MS has been aware of this issue since WP7, so I'm hoping they aren't just ignoring the community on this one. Another issue I seem to be having is that MS doesn't want my money......in that for whatever reason the windows marketplace refuses to allow me to add the credit card I usually use for those types of expenses to the WP8 "wallet" and thereby use it for app/game purchases. So far I've had to use a different card which appears to have no issues whatsoever. The credit card refusing to work with WP8 has never had issues with either the apple or the droid stores so I know it's not the card. I have contacted MS several times with regard to this issue and it is currently in an "escalated" state (whatever that means).
As I stated earlier in this thread I will post updates of my use of the Lumia 920 as I go along, and any issues I am having with it. I still (even after experiencing the above noted issues) cannot recommend any other smartphone over the Lumia at this point. That may change in the future, but as it stands right now the 920 remains the clear "smartphone of 2012" for me.
