If you love the idea of a quad cortex but find the grey a bit uninspiring, consider this black and gold limited edition version instead! Only seen home use. Aside from being a fingerprint magnet, the only sign of wear I could find was a tiny chip below the volume dial (pictured). I've disconnected it from my account and it's running version 4.1. I've deleted all my presets too. I.e. you could do a factory reset if you want a clean start but you shouldn't have to.
