The bosses who are actually in charge likely don’t even use their Macs (and when they do, they only use the web browser) and only care about how the OS is going to look in the demo, not how it works.
Pretty sure Tim Cook has said before he does most of his work on the iPad; it doesn't seem like an unreasonable guess that too many of the C-suites do the same and don't use Macs enough.
