Said elsewhere in this thread, but firewire/IEEE1394 wasn't hard to find in a PC/laptop, it was Windows support at all for the iPod that changed things. Once Apple shipped the Windows version of iTunes they were off and running.
I remember at the time many of laptops that had a IEEEE1394 port had the small size one, not the full-size one that the iPod cable used. Also most desktops didn't have it onboard due to royalty fees so you needed to buy a PCI card. Not an insurmountable obstacle, but enough that you had to really want one to look past that.
