Last year at CES, Razer revealed the Nabu smart band aimed at gamers to track their fitness (or lack thereof) and send notifications via an OLED display. The model still isn't on sale in stores, but that hasn't stopped Razer from launching another model: the Nabu X. It said the goal with the new model was to "eliminate ... price and complexity," so it killed the display of the original model in favor of three simple LED indicators. That means no more message previews, but the new model does everything else: vibration and LED notifications, fitness tracking via a built-in accelerometer and social sharing using a Bluetooth-connected smartphone. It'll run 5-7 days on a charge, with 30 days of standby time.
