I personally prefer a snifter but I primarily drink heavy stouts. otherwise a standard pint glass works. As far as the comment regarding no good beer comes in a can...there actually has been a can revolution in the craft beer space, there jury is still out on the cellaring ability for cans but for beers that aren't meant to be aged i.e. IPAs, pilsners etc. cans are a fine way to package and keep costs down. I will now get down from my soapbox
For me it is out of the can or bottle but if it has to be in a container I prefer a frozen mug if in a restaurant/bar or a Red Solo Cup if at a party/tailgate.
