I'm still trying to decide whether or not to give up my expresscard slot for an SD card slot. If I could figure out something useful to do with it, that would persuade me. I don't do hard core photography yet, and if I did, I could always just USB the camera. Does anyone use the SD card slot for something other than photography? I figured maybe it could be used like a floppy drive to organize certain projects or files but those could always be backed up to CD/ DVD. Not to mention, if you store the files on your hard drive, time machine would back them up.
