It depends on what job you have, unfortunately, and in which country.
That said, yes, if the Vision Pro can replace any number of monitors of any size, then for people who can afford it, it can actually be a bargain. Especially if said people both need both a lot of screen space and to travel.
Of course, the OS and its apps need to be as useful as MacOS and its programs (or are we calling everything "apps" now? I guess we do).
I've been a PC guy for the past . . . my God . . . 34 years. I'm what you'd call a power user on Windows (which doesn't mean I like Windows, just that I know how to deal with its many quirks, even when that means going back to DOS mode), yet the iPad Pro could have made me switch: I was really impressed by the hardware and might have gone to the Apple side it had been possible to use MacOS on it, in addition to iOS.
(Windows, ironically, can easily switch from tablet mode to PC mode, but the hardware isn't up to the task: nothing on the PC side today equals even the "old" M1 for power efficiency, and the app offering for Windows tablets is laughable compared to the app offering for iOS.)
I'm afraid of a similar situation with the Vision Pro: Even if it can replace a MacBook hardware-wise (which doesn't just necessitate a powerful processor, enough RAM, and a big enough SSD, but also all-day comfort for the eyes, head, and neck), will it be able to replace a MacBook OS-wise?
The iPad Pro still can't.
Right now, Apple expects most people who buy an iPad Pro to also have a MacBook (or a Mac mini, or a Mac Studio). If, likewise, they expect most people who buy the Vision Pro to also have a MacBook, then the Vision Pro is no longer the potential bargain I was mentioning in the second paragraph of this ridiculously long first post.
