Saw these cute retractable USB and FireWire cables INCLUDING a tiny adaptor in each package to make the cable work as the other type (i.e. convert one end of the USB cable to the square type or convert one end of the 6 pin firewire to 4 pin).
I just purcahsed a 4 pin to 6 pin firewire converter because my VAIO laptop has a gay 4 pin but my g/f's iBook has the normal 6 pin as well as her external CDRW. I paid $10 for that little adaptor and saw that I can get it, and a cable for $20 at Fry's (outpost.com). Same with the USB thingy.
It's Macally.
Anyone use these cute, cool looking cables?
