The original iPhone didn't nail the form factor. At the time people criticized it as being too wide to comfortably fit into one's hands since it was ½-inch wider than a standard cell phone.
Within a couple of years, the industry trended towards larger phones -- phablets. Criticism of the iPhone changed from "too small" to "not large enough". Apple resisted the trend for 7 years until the iPhone 6 Plus in 2014. Now, most iPhones fall into the category of what was called a phablet a decade ago.
Besides the size, other design criticisms were:
• Too slippery, too easy to drop.
• No hardware keyboard. The on-screen keyboard was too small for normal sized fingers. There was no tactile feedback from it. As designed, it was considered useless for real work.
• The battery was not removable. You will be tethered to a charger if you want to use it for any length of time.
It seems the Vision Pro is getting much of the same criticism. Perhaps you don't see it as being in the same ballpark because the extremity of your criticisms are out in left field.
I didn't say criticizing a first-get device is inane. I said "Criticizing the device for not being perfect on first release is inane." I stand by that comment.
