Pros:

- Awesome display. High PPI, ultra sensitive.
- Best camera on smartphone yet.
- Nokia build quality (really great), awesome reception.

Cons:

- WP8 is not at par with competing OS.
- WP ecosystem is yet undeveloped. Good quality apps missing.

Summary:

The Lumia 920 is the best Windows Phone out there. It's sexy, but big. Very big. Uncomfortably big. This is mainly to the awesome PureView camera included. Definitely the best camera on a smartphone ever, but not yet a DSLR replacement. Its fast, really fast, and the screen is awesome. The problem here is with its OS. WP is yet in its baby-steps. As well as the ecosystem. Many good quality apps are missing and I hope this will improve over time.

If you have big hands, and want to get a WP, this is the phone for you. But if you are looking for a safer bet, something you know it won't go wrong I still recommend the iPhone 5. The Lumia 920 is the best Windows Phone out there, and one of the best 2012 smartphones.. but its still evident the lack of high quality apps and in todays world a strong ecosystem is key for a smartphone to triumph.
