Dell has unveiled a concept laptop featuring a 16-inch OLED screen showing what could be possible in the future for notebooks. 

Packed into a Studio XPS 16, the OLED is just 2mm thick and comes with virtually a 180-degree viewing angle.

If that wasn't enough to get you giddy with excitement, the screen offers a contrast ratio that exceeds 10,000:1 and come with a response time of 0.004ms, 1000 times faster than current LCD technology.

The only concern we have? It means virtually everyone on the train is going to know what you are working on.
