I got my black back installed, I find the HDR "on" works well in low light, I'm using my touchstone as a dock. All that's left is to get the inductive charging wired up. Battery life has been so good that I'm not in a big rush, but I miss the convenience of just setting it on the touchstone on my nightstand and waking up to a fully charged phone.
I have a developer edition, so the white back was my only option unfortunately. How difficult was it to replace the back? Did you beat up your phone at all while doing it? I've opened several iDevices, but they always seem to have marred edges or tool marks when I'm done.
I'll have to try the "HDR on" option in low light. Sometimes I get good shots, and sometimes they are very dim or washed out.
For the inductive charging: I assume you're going with the same solution as Puzzlegal, or are you doing some modding of the phone internally?
Agreed that the battery life is very good on this phone. I'm coming from an HTC Thunderbolt, which is notoriously tough on batteries. I love the wireless charging, but could do without if I wasn't afraid that I'll wear out my USB port like I have on 2 Thunderbolts.
