The Apple Watch, originally announced in September last year, is to go on sale in Australia, Canada, China, France, Germany, Hong Kong, Japan, the UK and the USA from Friday 24th April.

Doro has announced plans to launch a mobile-based DIY care service this summer. It’ll combine social networking with a network of volunteers, ensuring that elderly people can receive assistance even if their friends or family aren’t available.

The service isn’t just for emergency use but is also designed to help when family members need a hand with domestic tasks, such as closing a window or moving a heavy object.

HTC has announced plans to launch its own virtual reality headset this year, with a ‘developer edition’ this Spring and a consumer version by the end of 2015.
