"ChromeOS wasn't designed as a touch OS..."
It is pretty good though. The new Samsung Pro and Plus Chromebooks are pretty slick as touch devices. I'm sure that Chrome OS will continue to get better and better with touch now that Android apps on available. Google moves really fast on dev cycles. Chrome OS revs every four to six weeks. If you have had a Chromebook for a year or more, you can almost see it getting better and more functionality in real time.
