"Better uprooted than dead." Being human has driven that home, and Zack can't help being his usual blunt self. He still thinks the thing should be destroyed but knows it's not on to wreck other people's property.

He too balks at the machine thing. Advanced tech generally goes way over Zack's head, unless he can see the thing, and if someone explains how to use it. He can handle the PINpoint and its little icons, or speaking into it. Dean was patient while showing him, and Zack does have a sharp mind, he can figure things out pretty well once he has the basics. Going blind though... that's not good tech, surely?

"'Kay," he responds to Dean, draining his coffee and fishing in his pocket for the PINpoint. He's grateful to his friend for not letting on that he's illiterate, and will repay the favour by not discussing the mountain of stuff they probably need to shop for. "Want me to come with you? I can help out."

After three cups, he's feeling very lively and willing to assist.
