Who said the Lumia 920 off-contract and sim-free is $800?
Right now the only allure to signing a two-year contract minus the price cut is a device with the proper LTE radios for use in the US. If the Nexus 4 that is coming out next Tuesday had LTE in it and still cost under $400 that would be one heck of a deal. LTE on AT&T isn't available everywhere I'm at, but I only have to drive ten minutes from my house to get into decent LTE coverage. If that wasn't the case, I might have considered picking up the Nexus 4 from the Google Play Store and using it.
Right now I'm just impressed with the build quality of my 920 and its black matte finish. I could see the benefit of having bought a more vivid color - yellow certainly comes to mind - but it's just loud. I like the muted appearance of the matte finish and how it just blends in with my workstation at the office. The cyan of my 900 just gave off the vibe to people I had my phone on my desk. Right now people cannot distinguish it from another phone model. (And that is OK)
Once someone sees that gorgeous screen power on and the camera in action I'm sure there will be no mistaking what kind of phone this is. Now, if Nokia releases gel cases like they did with the 900 and you can swap out for a red, yellow, black, etc and go with another accent color I'm game.
