I really hope they improve the post-shot sensitivity to light that seems to be the main culprit in my getting reproducible shots. The process is so variable right now that I feel the film is in control, instead of me, the photographer. I've tried the various methods posted about limiting light exposure - taping the dark slide to the front, flipping the image down while waiting to process, and none of them work reliably well enough where I feel confident that I can take the same shot two times in a row, and get nearly the same result each time.

That to me is the fatal flaw right now in the "first flush". Refine the film to the point where the photographer actually has some more control, and can actually watch the image develop (isn't that part of the fun of Polaroid too!?!), and I think TIP will have a winner.
