Show different theme for admin?

I just wrote this quick plugin and it seems to work. Let me know if there is a better way.

<?php

/*
Plugin Name: Theme Switch if Admin
Description: Display different theme to user if logged in as admin

*/
    add_filter('template', 'change_theme');
    add_filter('option_template', 'change_theme');
    add_filter('option_stylesheet', 'change_theme');
    function change_theme($theme) {
        if ( current_user_can('manage_options') ) {
            $theme="twentyeleven";
        }

        return $theme;
    }
