Notebook is made more and more exquisite, the function is more powerful, and the smart phone also has a tendency to develop towards miniature computer. Perhaps very soon, there will be no such thing as notebook and mobile phone. The new products in our hands can be a mobile phone when folded up, and can be used as a notebook when unfolded. This slidable notebook computer may be a solution. It has a 9-inch touch display screen and can video chat via VoIP. It has the general function of a computer. If the mobile phone function is also added, it can actually be used as a computer and a high-performance mobile phone.
