i played with this a bit...
the build i got last night seems stable and good.. music app brings be back to "android" boot animation and requires a reboot - but playing mp3s via file manager is good
wifi, bt work good...
performance is good
stability is good
and the ONLY time i really use benchmarks is to test what how a change i made in a kernel affected things. i use the same exact rom and to a fresh install each time w/ a full wipe. and quadrant is the last one i use..
and for a stability test i run 1 benchmark after the other, with as little as a gap between each one as i can, and run linpack 3-4 times in a row - THEN i run a stress test app
