The Surface computer first previewed by Microsoft last year has made its debut as a working computer in Las Vegas. 

Designed as an interactive bar table, customers at Harrah's Entertainment can order drinks, watch YouTude, play touchscreen games – and even flirt with each other.
For Harrah's, the technology lets it keep track of its customers' behaviour, forming part of its customer rewards programme that already tracks their gambling habits.
The six table feature 76cm flat screens using Microsoft Surface technology and cost about $10 000.00.
Companies can customise the Surface computers to meet their individual needs.
Although the Surface functions like a computer monitor, it can also be used as a regular table, so customers can put their drinks on it.
