Normally I reference my media query like so...

    <style type="text/css">
    @media only screen and (max-device-width: 480px), only screen and (max-width: 480px), only screen and (max-width: 568px) and (orientation: landscape) {

    STYLES GO HERE

    }
    </style>

...but would there be anything wrong with me referencing it like this instead:

    <style type="text/css" media="only screen and (max-device-width: 480px), only screen and (max-width: 480px), only screen and (max-width: 568px) and (orientation: landscape)">

    STYLES GO HERE

    </style>

Would this limit the amount of devices which pick up the responsive version? I've done some Litmus tests and it seems to make little difference (especially across iOS) but I thought I'd double check.
