Sandy Bridge got nice reviews yesterday, but includes DRM:

Seems to me that it is some sort of system for streaming movies, like Steam does for games:

Anyway, we will probably know after the CES press conference.
It seems that there are trouble with some Sandbridge MB’s and they will have to recalled.

Yes, the trouble is with the SATA-2 ports. My mobo has am additional 4 SATA-3 ports that are OK, so I am fine until I get a replacement.
But no Sandy Bridge mobos will be exchanged or sold until they get new ones sometime in April.
Shi*t 
At least Intel came clean when they found out.
I feel sorry for you
