Lenovo Vibe Band VB10Lenovo’s new E-Ink based, curved screen fitness band is one of the most striking uses of E-Ink in a wearable we have seen to date. The Vibe Band VB10’s power-sipping screen is housed inside of a metal case, has a rubberized strap, and weighs a mere 30grams. Thanks to the E-Ink screen you can expect around 7 days of battery life from the $89 fitness band. The VB10 is able to track steps, calories, distance, and sleep quality in addition to receiving notifications from your smartphone, via Bluetooth 4.0. If all that wasn’t appealing enough at that price point, it is also waterproof. Unfortunately when the fitness band launches in April it will not be coming to the US. Lenovo currently has no plans to bring it to the US market.
