Different Skin for different screen res

[Adam H]

Hey everyone , Does anyone know if its possible to get the browser to auto detect screen size when they hit the site and default to a certain skin ?

basically some of my users have those new tiny Netbooks, But because of this their screen res is far to small to see the forums properly with Navigation menu's clashing , So i want to create a new skin which is extremely cut down and only display it to those that need it.

I dont want the skin to be public though it has to be auto detected etc.

Any ideas ?
