German keyboard maker Das Keyboard launches the 4th version of the typing device sharing its name-- the Das Keyboard 4, now with an anodised aluminium top panel, dedicated media controls and an hifi-style volume control knob.

It carries Cherry MX mechanical switches for improved tactile response and satisfyingly clicky key presses, as well as an extra long 2m cord and a magnetic foot-bar holding the it up at a "perfect" 4-degree angle.

Gbatteries claims the BatteryOS technology inside the BatteryBox rechargeable Lithium-ion battery pack not only keeps devices running for longer also help reduce battery degradation.

According to the company the BatteryBox carries 50Whr of power-- enough to run a MacBook Air for 12 hours, a MacBook Pro for 6 hours or charge up to 8 iPhones.

As well as iDevices equipped with a MagSafe 2 port the battery also charges anything equipped with a micro USB port. It weighs250g and takes 9 hours for a 100% using a 1A power supply.

Android already powers a number of smartwatches, but now Google announces a version of OS tailored specifically for such devices-- the perhaps self-explanatory Android Wear.

As seen in a typically slick demo video, Android Wear pushes location-based data from smartphones to smartwatches together with the usual bevy of message and social network notifications. It features a Google Now-style UI users and allows natural language input via the "OK Google" prompt.

According to Google it also handles functions such as health tracking and connectivity with other devices, such as summoning a playlist from a mobile device or pushing a video to a TV, while being extremely power efficient.

According to Razer the keyboard is ripe for a redesign aimed at PC gamers-- specifically the Razer Mechanical Switch, an overhaul of the humble mechanical switch found in most keyboards.

For the curious, most keyboards on the market carry Cherry MX switches. But not the recently launched Razer BlackWidow keyboard, whose switches promise "a lighter and smoother feel" according to professional StarCraft player Jens "Snute" Aasgaard.

The Razer switches come in two flavours-- "tactile and clicky" Green (requires 50g of force to actuate) and "tactile yet silent" Orange (requires 45g of force).
