Color Polaroid images have a well known propensity for blue shift. I was one of those people who had to have the camera, and I got the folding one and spent lots of money on film packs. Great concept, I still have them, but to make them look good, I have to scan them in and Photoshop them.
My feeling is, the benefits of digital far outweigh the disadvantages, in my case at least. I am immersed in the digital end of things, I understand formats and migration.
I have my files backed up on two separate hard drives, I have them all archived and burned to DVD's which I have placed in my Safe Deposit Box at my bank.
But these are all good points people make. I will wait until the 3D Transparent Cubic storage units come out, because they will certainly last for a thousand years...:)
I plan to beam all of my important data into the Phantom Zone, where time stands still for all eternity.
