Those models died a death pretty quickly due to the high cost and were extremely niche. Hopefully those are not a good comparison to a headset that seems massively overpriced at this point but may have some market potential.
However, functionally the more expensive watches were identical to the cheaper versions. A fairer comparison may be to the original MacBook Air. When it was released in January 2008, the base model was $1,799 (about $2,500 today), and the 64GB SSD added another $999. By November 2008, a significantly revised version with a 128GB SSD sold for $2,499 (about $3,500 today). By October 2010, the base Air was down to $999 (about $1350 today).
While I don’t see the Vision Pro price declining at such a steep pace as the MacBook Air, I do see room for a “Vision” (”Air” or sans Pro), or even a “Vision SE” in a few years at more affordable price points. Apple seems to be fitting the original Vision Pro with the best available equipment (M2, new R1, micro-OLED screens), perhaps to avoid some of the issues with the original Air and Watch, but still the first versions are likely to be buggy and sell in relatively low volumes. I think Apple expects that. It took a few years for the Watch to gain traction, but today it’s an important part of their product lineup. Apple will make a similar long-term commitment to the Vision lineup.
