I do agree that polaroid was an important and useful invention in its time. The only problem is the short life-span of the photographs. My parents themselves lost a lot of wedding photos (taken by friends) that simply faded out of existence over the years.

I very much agree with Bobdoom in that it is a wonderful form of alternative photography that was, in its day, particularly gratifying because you got to see your pictures so quickly! The grainy effect was also very cool. I think that polaroid can be a lot of fun these days, particularly that we now have nice scanners to immortalise out pictures!
