Same.
Same.
I feel the same thing is repeating with Thunderbolt.
It's kind of funny/sad because neither technology is strictly tied to Apple machines - I had a work laptop (Dell Latitude D630) with a Firewire port. One of our CAD workstations has Thunderbolt on board (but, sadly no actual port).
But there were almost no peripherals to support it. The only person I ever saw using Firewire used it to transfer digital video from their camera to their PC.
Firewire was heavily used for digital video, still used for heaps of industrial cameras. Still very prominent in digital audio. The multimaster bus design, guaranteed timing and bandwidth (isochronous transport), and speed, made Firewire a winner. A Firewire 400 drive is practically twice as fast as USB2. So anyone who had to do lots of transfers used it.
