It's a good question. Even modern video editing houses are content with 10Gbe to workstations, and most of us aren't modern video editing houses. Even Wi-Fi can reliably deliver speeds at or near the gigabit. No, you don't need fibre to your desk. But don't tell me you don't fancy it anyway, just for the geek of it. And that's the real reason Cisco has done this. It's not one that fits onto spec sheets or use cases - not today's use cases, at least. It has to know why and you have to know how a piece of solid-state physics is creating quite a battleground in the data centre, one where Cisco is locking horns with Intel, and how some long-term bets may be about to pay off. But in the end, it's all down to the photon versus the electron.
