>The whole point of Vision Pro like devices is you wear your computer on your face always with you and the only peripherals you need are your eyes and hands also always on you.

Clearly not, as the Magic Keyboard and Trackpad are well integrated (as is just using your laptop trackpad and keyboard). It's akin to using a keyboard folio with an iPad. It's a fully usable product without it and tons go without, but the keyboard folio definitely unlocks additional potential.

The Ibiza-appeal would be that you can have a small backpack of stuff that lets you reach full productivity on the beach. I can't carry monitors the size I'm able to pop in on the AVP. To answer your question downwind, is it the same as like, an ergonomic desk set up? Nah. But it's pretty cool and surprisingly usable in many cases (this tricky spreadsheet is notable for not).
