To create a "head." Explained in Wikipedia: "The can is pressurised by adding liquid nitrogen, which vaporises and expands in volume after the can is sealed, forcing gas and beer into the widget's hollow interior through a tiny hole. When the can is opened, the pressure in the can drops, causing the pressurised gas and beer inside the widget to jet out from the hole. This agitation on the surrounding beer releases nitrogen that is dissolved in the beer, creating a creamy head inside the can. This imitates the foamy head created when pouring draught beer."

It is suppose to preserve draft like qualities and make the brew out of the can taste virtually the same as a Guinness on tap.

To make the can version closer to the version from the pub so you are more likely to drink it in a pub - an advertising ploy in other words

To confuse you into thinking that you are drinking the real thing. Sadly, you are not. It's the beer drinkers equivalent of a wet dream.
