html - Using media queries to target either smartphone OR desktop/laptops without pixel sizes

Question

Today, smartphones have very high pixel densities, and a lot of answer on media queries are answered with screen sizes.

I'm using this:

@media handheld {
    p {
        font-size: 300%;
        max-width: 100%;
        margin: 1em;
    }
}

Which only applies to smartphone browsers.

How can have a media query that applies only to non-smartphone screens?

I tried

@media not handheld {
    p {
        font-size: 50%;
    }
}

But it doesn't work.
