This blog post is about touch screen Macs, but I’ll start by talking about touch screen cars. Vehicle manufacturers have increasingly replaced physical controls in cars with touch screens, and it hasn’t gone well, because the touch screens frustrate drivers. As a resident of the Upper Midwest who drives wearing gloves in the winter, I suspect that the idea for touch screens came from somewhere warmer than the traditional home of the automotive industry, Detroit. For further reading on the serious, indeed dangerous problems with touch screens in cars, I found a couple of recent articles from Popular Mechanics and The Conversation.
