java script if clause

I have line of information I would like to leave out if the site visitor is looking at a site via an ipad. Is there any java script that will allow me to do this:

if !ipad "some string"

Thanks,

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

to make it slightly more robust you could make the regex case insensitive:

/iPad/i instead of /iPad/

Thanks basicinstinct,
if I wanted to echo an alternate style sheet using your code how would I do this?
IE
if(!(/iPad/.test(navigator.userAgent)))
{
<link rel="stylesheet" href="css/style.css">
}
Cheers,

well normally that would be done on the server side,
but for argument's sake if you want to do it on the client side then you could do something like this:

(function(){
if(!(/iPad/i.test(navigator.userAgent)))
{
    var newCss = document.createElement("link");
    newCss.setAttribute("rel", "stylesheet");
    newCss.setAttribute("href", "css/style.css");
    document.body.appendChild(newCss);
}
})();¿

That's perfect and extremely thorough, thank you.
I am guessing that an alternate method code be:
 if(/iPad/.test(navigator.userAgent))
{
document.write("<link rel=\"stylesheet\" href=\"css/device.css\">");
}
        </script>
