Why do you think so? There's a pretty explicit qualifier that seemingly distinguishes that the snarfy hates all touch screens, especially when they're in cars. I'm responding explicitly to the first part while ignoring the second half, with which I somewhat agree.
If I can use something else I will. Phones are small enough there really isn't a better alternative to a mouse, but I would still rather have a physical keyboard than a touch keyboard. On laptops with touch pads I always connect a mouse. If it's a laptop or desktop with a touch screen, the last thing I want touching the screen is my greasy fingers. I have a mechanical keyboard and gaming mouse for a reason. They are superior input devices.
