Approaches to handling Mouse AND Touch Events

Target Platforms Mobile

Building my first mobile app and surprised to find out that Mouse events are not automatically converted to Touch and detected when I deploy to my Mobile device.
After some googling came across this solution (from Unity Answers)

Can any experienced mobile developers comment on whether this would be considered ‘best practice’? Or is there a better solution?

//  OnTouchDown.cs
//  Allows "OnMouseDown()" events to work on the iPhone.
//  Attach to the main camera.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class OnTouchDown : MonoBehaviour {
   void Update () {
       // Code for OnMouseDown in the iPhone. Unquote to test.
       RaycastHit hit = new RaycastHit();
       for (int i = 0; i < Input.touchCount; ++i)
           if (Input.GetTouch(i).phase.Equals(TouchPhase.Began)) {
               // Construct a ray from the current touch coordinates
               Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
               if (Physics.Raycast(ray, out hit))
                   hit.transform.gameObject.SendMessage("OnMouseDown");
           }
   }
}

I pretty much exclusively get ‘pointer’ input through the EventSystem. It handles touch and mouse the same way.

Have you tried any of the many assets in the asset store?
