We've had trouble with _all_ capacitive touchscreens, from a durability
standpoint, although two months isn't our normal design requirement.  The only
screens we've found that simply don't physically wear out are the LED
break-beam screens, such as the CarrolTouch.  But I don't know about
availability for the Max.
