Not being sarcastic, just wanted to know what the current uses are and if anyone can't live without it. I ordered a BTO 2011 17" and was a little bummed to lose the sd card slot but am intrigued as to what I may have gained. All the express card threads are pretty old and don't really address why a high end machine that was just refreshed days ago saw it fit to keep this tech. Is this tech dead? Are new developments coming? Or is this just a tide over until thunderbolt peripherals outweigh esata express card adapters?
