My feel is the "feel" segmentation is like this:

MacBook Neo: for students (some primary school, probably more geared to post-secondary) and people who want a lightweight (form factor, price, performance) laptop that still feels premium.

MacBook Air: people who frequently move around, have an actual need performance but in a highly portable form factor.

MacBook Pro: professionals who highly prefer performance over ergonomics, basically a portable PC, as they likely keep it plugged in more than not, and it spends more time on a desk than being used as a laptop.

Basically the Pro is like a PC that also happens to have a screen and a keyboard and foldable, the Air is their laptop that intends to be a laptop, and the Neo is their Air on a budget.
