It's currently lying in the corner whilst I try to stomach paying £25 for a third-party cable made with their custom internal connector.
I'd prefer if they just had a USB female socket on the keyboard and then I could use any cable.
Why do keyboards have hard-wired cables anyhow? They have plenty of space for a socket and it would eliminate another point of failure.

Captive cables only need enough copper to supply enough current for the device they're built into.Separate cables, OTOH, need enough copper for 500mA with a certain voltage drop to be USB standard compliant. Means 24AWG or bigger for a 2m cable [1].
That's why your keyboard, mouse and webcam have skinny cables while other USB cables are much thicker.

Low-speed USB devices are not permitted by the spec to have a detachable cable. The fancier keyboards are probably full- or high-speed, though, so that doesn't apply to them. As someone else said, mechanical strength may have something to do with it. Keyboards get shoved around a lot, and a connector would likely break off too easily.
Personally, I'm of the opinion that even tenkeyless keyboards are too wide for most right-handed users - unless you're very broad-shouldered, you'll either have to skew the keyboard to the left or use your mouse too far to the right. 60% and 68% keyboards offer real ergonomic benefits, by simple merit of being narrower.

The only issue I have with it is its cleanliness, need to take it apart and give it a good scrub again sometime. There's also some rust on the base plate, probably because I scratched the paint at some point. But that's not something you can see or is a problem when using it.
It's mostly for leisure though, at work I've got an Apple wireless keyboard; the low profile works for me to prevent rsi issues.
