Yet most corporations only give laptops to employees whose jobs involve travel - everyone else gets a sub-$1k Dell desktop, with a hand-me-down display. This is the segment he's suggesting Apple address.

Laptops for everyone would be awesome, but hard to justify if they'll never leave the office.

By including the display on the iMac, Apple ensures that they sell a display with each unit shipped, they maintain their volume discounts in the supply chain, etc. This is just conjecture on my part, but it wouldn't be surprising.
