From the volume ago has become the predecessor nothing changed. However, if you in high speed data reads for example an ISO to create, so I find the vibrations disturbing. This was the predecessor too. You just have easily tap your finger on it and they disappear. Well, now is a wooden table, but with the corresponding weight / rubber feet usually does not happen like that. But it is for small and mobile, so I will not complain about it once.
I would in any case also so wish me for the BluRay drive housing.
Update:
Also check out the new DVD slot-in burner at times. The now surrounds a complete metal part.
