It's True: The ruling gives nVidia a 'Cease and Desist' order because they weren't paying Rambus royalties on what ended up being judged as Rambus' Intellectual Property. The end result will involve large sums of money moving from nVidia to Rambus, and the end consumer will be inconvenienced with slightly higher prices and possibly a short interruption of the flow of parts.
Business as Usual, tho: Just RAMBUS bending another corporation over in Patent court. They're not a technology company any more. Rather a bunch of professional patent trolls.
