What's icky about taking a laptop down to the park and getting some work done while surrounded by nature?

Although, I do agree, I would find it odd to go down to the park and see someone wandering around with a VR headset tuning out the world and waving controllers around. I'm more addressing the "cowork in public spaces" part of that. I think their statement about "while traveling" is more like while seated on a several hour plane trip or relaxing at a hotel or things along those lines. Not like wearing the device while ordering a latte or something along those lines.
