I borrowed a Lumina 920 for about a week and
really liked it. Well built, cool UI. I especially liked the calender. The lack of native google apps didn't bother me too much. I've got waze to replace gmaps, the lack of a non-sketchy looking gchat app was annoying but that was about it. I can use the services I care through the browser and my email and contacts synced just fine.
The real killer for me was the lack of a keepass app that supports 1.x DBs. If any of y'all are looking for a project, do that! You would have earned my $1!
