I've had three touch screens fail this year, one on my car GPS, One Cellular telephone, one on my wife's Kindle. I'm not real excited about touch screens at this point. They may work fine for Diki, but for me, I'll stick with those archaic buttons and switches. No failures in 20 years.
Cheers,
Gary
