I've tried most of the so called blurless roms
and most work ok but have some wonky bugs
after taking a little time and diving into the stock OTA 2.2
it seems to me and my medium level programing knowledge that motorola has
put BLUR very deep into the functions of the phone.
so by removing all of blur or even large sections of blur their code seems to
reply on system checks. meaning one aspect of blur looks for other blur programing in the phone. IE i believe the camera blur app has code placed in files outside of the blur camera.apk making a blurless phone act funny.
would make sense to protect their custom UI by writing syntax calls into every aspect of blur.
again just my thoughts on this I could be wrong.
