Tried it out. Hardware functions seem to work well. Was able to Bluetooth pair with my laptop and transfer a file (can't find my headset ATM). WiFi seems to work well, GPS lock was quick indoors. I don't know if it's just the weather or what, but GPS seems better than CM7. That is, if I exit Maps and do some other stuff for a few mins, CM7 would always try (and struggle) to locate me again, even if I haven't moved. This ROM seems to retain that info better, if that makes any sense.
Status bar notifications seem to be working. My wifi icon turned green when connecting to Google services, but not the signal bars--don't know if that is by design.
Power widgets are nice and work well.
Sent and received an SMS without problems.
Really like the slide up dock tray in the launcher!
Forgot to test hotspot...
hope this helps some
Edit: but yes, there are a ton of Google framework/Apps FCs, which you already know about.
