ICE Trinity™ X-101 is a novel “post-pc” device, which serves Smartphone, Pad, and PC functions. It is eco-friendly and supports “Brain-in-Pocket” – a portable device that allows users to access the Internet, communication and entertainment (ICE) anytime anywhere. This mobile platform's main features are a multi-touch display and a slot located on the back for accommodating various “brains”. The plug-n-play device is eco-friendly as it shares the platform among “brains”, which not only resolves component shortages for manufacturers and removes the need for investment from consumers, but also supports dynamic functions and makes upgrading much easier and more cost-effective.
