I would agree with you on this Paul. I have recently benched my first LightSYS with the touchscreen. I am familiar with the programming side of it after using the Agility, but was slightly put off by the performance of the touchscreen while programming. Not to mention I am having to return it because the screen display has gone blank.
I am of the opinion that the end user will want the touchscreen because of the gadget world we live in now, as long as they don't experience any problems putting a code in or using a tag, then they will be happy.
