ADB works. On the 3rd attemp doing a factory reset also worked. N.b. this is now under "Privacy" and not anymore under "SD card" where it used to be once.
Factory reset worked. I got some inconsistent stuff on the first attempt. Coming from a 2.21 ROM it seemed things like that Data Meter were still there. After the wipe it was gone. IMHO one needs to do a wipe before flashing this ROM.
Camera works. The interface has changed. There doesn't seem to be a quick upload via MOTOBLUR anymore (needs to be rechecked; also the facebook upload is missing; maybe a delete/add of the facebook account gets this back). The camera interface & librararies are similar to the Droid X as well as to the 3.6.390 update (yes, the one I could not install because I screwed up my boot loader).
Quadrant is around 1100 for me, which is the same as with 2.21 and the dalvik updates. Looks also like a few OpenGL ES 2 bugs have been fixed ;-)
Cityville works, which means flash 10.1 is fine and dandy (no comments please, farmville is blocked ...)
The gallery seems to still have issues. Some of the pictures I took the other day with a 2.21 rom are not shown. Same goes for some of the ripped DVDs. Puzzeling. Upload via facebook fails.
