That's not what I was saying. Palm and RIM assumed their unit sales were an unassailable moat. Both almost completely ignored the consumer phone market then dominated by feature phones. Apple didn't jump after raw market share but an underserved market.
I'm not saying the Vision Pro will follow the same path as the iPhone. Past sales of the competition shouldn't be used as a signal of how good compelling of a product it will be. Meta's sales reflect the demand of a product from Meta. Apple has a lot more experience and success at building a platform for third parties. Meta can improve the Oculus platform but it's an open question whether they will.
