I think the touchbar is the way to go for desktops and laptops. You can imagine Apple rolling out a touch bar enabled desktop keyboard. But touch screens are totally impractical for use when your computer is docked, which means you can't really incorporate them into your workflow.

The battery life point is really depressing. Every MacBook since the original has been improving on that front and this is such a huge regression. If I wanted just 5-6 hours of battery life I'd buy a PC.
