I don't know about you all, but whenever people see my yellow Lumia and say "that's a nice case!" I start bragging how it's not a case, and how wonderful the whole phone is. If I run into anyone that's not certain about the camera, I show them some of my videos. Any other phone out there is terrible at recording videos in loud settings, especially concerts or night clubs, the Lumia though, it records sound that seems better than what I heard with my own ears! lol.
Here's a sample of why I love the Lumia camera (watch on 1080p of course):

No issues with dust in FFC, and my battery goes down to about 60% or so by the end of the day, I still charge it so I don't have to carry a charger to work.
About lockups, mine hasn't locked up, but I had to do a hard reset a couple weeks ago and it took about 10 or so hours. My only problem with the phone so far, which is what caused me to do the hard reset, is that my Hotmail is not syncing anymore, the hard reset fixed the issue for a few days but it's happening again. It's a software issue though, which is why I never trusted WP8, but I do love the hardware on this beast <3
