Actually the cord on this keyboard if anything seems thick to me at almost 1/2 " in diameter. That's probably because of the connectors at the end though ( 2 usb, mic, and headphones). It's a braided cord and it started out pretty stiff but it's fine now after a few days.
I have really liked the quality of this keyboard so far. I haven't had any problems with it and it is pretty sturdy and doesn't slide around on my desk like my old rubber dome keyboard used to. I would have to say I like everything about this keyboard so far with the one nuisance being that the 3 indicator leds are pretty bright but not blinding at least. Other than that I don't see any major flaws to this keyboard unless you don't like the font used for the keycaps but I do so that's not a problem for me.
