Question: How long is the cable?
Document: It just is what it is, and I didn't have that problem with the plastic logitech.3) the cable is too long.I am really happy I bought this and I have  bought a second one already. If you want a wireless one I would still get the logitech.
As an Apple fan, I love almost very product they sell. In particular, this keyboard was with a very nice price.I live its design. It's light, very comfortable for typing and the cable is long enough to or it move freely on my desk.I don't have any complain about it. In fact I would recommend it. It would be more likely I would buy the wireless edition next time, when I get a really greet discount when available. :)
Thanks Apple for including this useless extension cable.
when your cat chews thru the cable to your keyboard, this is the perfect replacement. Came fast, and back up and running in no time.
Comes with a USB extension cable if needed. Only concern is that the white keys will become dirty. First world problems :p
Keyboard returned due faulty cable. Return was handled with Amazon's normal efficiency. Product was not usable. Payment return made promptly.
The keyboard is of high Apple expected quality and I love the light touch of the keys.I had to revise this review and up it a star after dinging it for a short cable.
I have the keyboard plugged into a Powered USB Hub, not directly to the MacBook Pro, so maybe that is the problem...  Not sure, the cable will not reach all the way to the MacBook Pro.
Apple keyboard is great and looks good. It has usb cable and ultrathin anodized aluminum enclosure with low-profile keys that provide a crisp, responsive feel.
Why oh why won't Apple make a wireless keyboard with the Numeric Keypad (numkey) attached? You can only (as of this review) buy this keyboard with a USB cable if you want the numkey. If you get the wireless version, you have to buy the numkey separately.
Answer: around 80 cm
