Harvard Business case studies cite the delayed Windows version as a marketing tactic. "Everyone loved" the iPod, and apparently quite a few people bought a prerequisite Mac in order to use the iPod.
Indeed. I looked weird on my college campus with a Mac. However, after the iPod the idea of using a Mac became more acceptable I saw a lot more of them. Now they are ubiquitous - something I would not have imagined 15 years ago.
I remember having to buy a firewire PCI port just to use my first iPod with Windows. It only worked sometimes, and I had to use some third party tool to upload music to it (or winamp, I think, had some limited support).
