The microdrive is about to get better. With the new "Pixie Dust" technology they are hoping to get them over 3 gig. The back I linked to is made to tether to a computer, so storage isn't really a problem, you just have to lug around a laptop. It only takes one shot at a time anyway because one shot fills the buffer. Unreal. I said the images would surpass film quality, but the equipment still has a lot of catching up to do. Speed and usable ISO are the limiting factors for really high quality digital sensors now, not resolution.
