Except that (as I recall) the floppy drive was completely obsolete when they did that, so almost no one cared. And the CD drive was not very painful either. The story is completely different for the headphone jack. It is not in the least obsolete, and it being missing is a huge pain for a lot of people.

It was a completely bonehead move on Apple's part IMHO. I know they had their reasons for doing it, but I still think it was a big mistake.
