I just came from a presentation purported to be about a stackable filesystem from Samsung called SynergyFS. The talk was more of a hardware sales pitch with no technical details, and technology that "can't be released under the GPL because if we give it to you you can give it to anyone else."
Samsung definitely doesn't get Linux and Open Source and deserves to remain on the "to avoid" list when purchasing new hardware.
