Worse, it shows how badly staffed the companies are, with a management that doesn't care about their staff skills.

From experience, I bet Apple and Microsoft have offshored all their desktop teams.

Windows went through a pendulum swing of integrating touch (I think they ended up in a place where they expect users to use more of a multi-modal approach instead of touch-only).

I suspect Mac is going through the same thing right now as ipad is "growing up" and they're trying to reconcile all their UI. I'm a little surprised that Macs have never introduced touch.
