> I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!

It amuses me that back in the 90's LCD color screens were magical fairy dust that cost about the same as what magical fairy dust would cost. Laptops with color LCD screens were like $6000 in the 90's, I think $3k over a greyscale. That's like $13k today.

Whereas the little plastic buttons and knobs were cheaper to pump out of an injection molding machine and assembled. Now screens are cheaper to make than little plastic baubles.
