I've had it installed as my daily driver (with another phone as backup) for a few days now. Overall, not too bad for a beta. Aside from the none-working things listed in OP's post, the following didn't work well for me.
1. Green tint with the rear facing camera.
2. WiFi Hotspot freezes and reboot sometimes.
3. SuperSU can't be installed, while the built-in root support is still buggy (or not compatible with some apps).
4. No App-2-SD option anymore. You have to format the SD card as internal memory to use it, but TWRP doesn't understand it. So backup and restore is a hassle with that approach. In the end, I left it as external and learned to live with smaller ROM.
5. The phone's ringer dies until reboot, if more than one app try to access it. I have Hangout (Google voice) taking my calls and at the same time forwarded to my phone number. Normally with all other phone I hear both Hangout and phone ring at the same time when my Google voice number is called, but with this ROM only Hangout rings. The normal phone app shows the incoming call but no sound. After that, even a normal incoming call doesn't ring anymore, only the display works. To live with this problem, I enabled the vibration, so at least I can feel it when a call comes.
6. Here map takes really long time to load.
7. No MS Exchange client. This can be solved with a service pack.
Does your camera allow you to focus at all? I am having an issue with the camera not focusing.
