What’s the Deal With USBs?

Ok, what’s the deal with all the USB accesories? I don’t get it. Everywhere I turn some designer comes up with an "uber" cleaver design or concept for a USB, what’s up with that? Who cares? Yeah, maybe that weird group of geeks in high school care enough to buy a (insert favorite thing here) USB gadget, but for corporate America? I just don’t see the appeal? Why spend money on a device that is going to be out dated in a couple of months anyway, when Apple comes out with some ultra cool and sexy alternative to USB’s?

Someone leave a comment and fill me in, please.
