Apple has decided to phase out Firewire all together on some models of its products like the Mac Book Air, in favor of USB 2.0, Not USB 3.0 and you don't get an Ethernet port either, or any kind of optical drive. About 12 years or so ago they had introduced Firewire 400, 800 & USB as standard ports on almost all of their machines. This was great then and kinda showed that Apple was ahead of the times at that point. Other great leaps ahead of the rest of once included Gigabit Ethernet on certain models. Looking at the newer Mac's I don't see any firewire 400 ports anymore. I see that some still have Firewire 800 so that's a plus, glad they haven't phased it out all together. Apple had many advancements over the competitors at one time. Whats so great about Thunderbolt?
