Odd first post here:
OS X is based on the CMU Mach Kernel. It predates Linux. And was used as the under pinnings of the NeXT computer, prior to Steve Jobs bringing those ideas back to Apple on his return.
So back on topic. I don't think that the BMCC will kill DSLRs for video. But I have to say that for what I want, it is nearly the perfect tool. SSD prices are coming down, and are cheaper than large name brand UHS-1 SD cards, so storage really is a non issue. I do 3+TB of still photos a year. Managing large disk arrays is part and parcel of what I do there, so adding a few more TBs is not going to kill me. It will also get archived and off-lined faster than the stills, which I need to keep 100% accessible for 2 years.
