Cordova "out-of-the-box" can't determine if a device is a tablet.

For iOS, a simple bit of Javascript can be used to detect if the device is an iPad by examining the user agent string:

var isTablet = !!navigator.userAgent.match(/iPad/i);

However, for Android, JS isn't good enough, it requires some native Java:

private boolean isTabletDevice(Context applicationContext) {
        boolean device_large = ((applicationContext.getResources().getConfiguration().screenLayout &
                Configuration.SCREENLAYOUT_SIZE_MASK) >=
                Configuration.SCREENLAYOUT_SIZE_LARGE);

        if (device_large) {
            DisplayMetrics metrics = new DisplayMetrics();
            Activity activity = this.cordova.getActivity();
            activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

            if (metrics.densityDpi == DisplayMetrics.DENSITY_DEFAULT
                    || metrics.densityDpi == DisplayMetrics.DENSITY_HIGH
                    || metrics.densityDpi == DisplayMetrics.DENSITY_MEDIUM
                    || metrics.densityDpi == DisplayMetrics.DENSITY_TV
                    || metrics.densityDpi == DisplayMetrics.DENSITY_XHIGH) {
                Log.d(LOG_TAG, "Is Tablet Device");
                return true;
            }
        }
        Log.d(LOG_TAG, "Is NOT Tablet Device");
        return false;
}

This plugin wraps up both these approaches in an easy-to-use package for Android and iOS: https://github.com/dpa99c/phonegap-istablet.
