Empty promises
Having years of personal experience with Riverbed and other vendors in the space, I can't believe they're still trying to make the outrageous and unfounded claims of bandwidth and latency savings that they are. They might as well claim to accelerate the speed of light while their at it.
Riverbed has been pretty lost for the last two years since no one decided to buy them, which was all they were hoping for in the beginning. Epic fail.
