   Both Firewire and now Thunderbolt are most-often found on Apple computers -   
   Firewire   
   was developed (and licensed) by Apple though I believe Thunderbolt is actually   
   an Intel-development.   
      
   (Sony also promoted Firewire for a while - mainly as a way to interconnect   
   Sony Vaio laptops with Sony video recorders).   
      
   Firewire was a more efficient data-transfer protocol than USB and as a result   
   Firewire-400 (rated at 400 Mb/sec) was (in the real world) faster than USB 2   
   (officially rated at 480 Mb/sec). However, USB had no licensing fees while   
   Firewire had a small ($2/system I think) fee... and in the low-profit world of   
   PC technology, free beats cheap.   
      
   Thunderbolt has some advantages; for Apple it allows them to use the same port   
   for Thunderbolt (connecting external hard drives) and for plugging in their   
   digital video adaptors - saving space in small form-factor Macbook Airs, for   
   instance. But because Firewire cables and devices require special built-in   
   circuitry they are inevitably more expensive than USB devices - as a result,   
   they're relatively expensive and hard to find.
