I think it's pretty clear that "the beach" here means your hotel room/airbnb. You wouldn't usually travel with your monitors, so you'd be stuck with your 14" screen. That's the use case this is addressing.

But also, I think it probably would work well for hammock beach working in Ibiza. The biggest issue seems like it would be tan lines, getting bullied for being a giant Nerd, and your spouse/wallet killing you for buying a $3-4k headset and an Ibiza vacation.

Does it? In my mother tongue "to the beach" means the place with sand and water, not the accommodation.

But if you imagine it said in a fancy accent by someone holding a stack of bills totaling $4000USD does it change the meaning? “On the beach” has to be in very posh accent.

You'll also have a really interesting tan line...
