If Apple could bring themselves to sell a lapdock, it'd have to cost at least $500. We know this because the Magic Keyboard for iPad, just a keyboard and trackpad, is priced at $349 (and it was introduced at that price way back in 2020, so at the time, Apple believed that keyboard was worth $440 adjusted for inflation). A screen to Apple's quality standards, even a 12-13" one, cannot possibly increase that price point by less than $150. So, the Apple in our universe could not produce a lapdock, because in our universe they have a whole laptop at that price point.

On second thought, the reality distortion field is real, so I suppose if they told people their new $600 lapdock was a good value even though it costs as much as the entry-level Mac, they'd still find willing buyers.
