For starters, they hear a tale from one Apple director about the special board meeting held after Jobs accepted the post. Jobs walked up to the wall of the conference room where Apple’s roughly two dozen current products were on display and began taking them down, one at a time. When he was done, only four were left. Those were the ones, he said, that would give Apple new life by differentiating it in the marketplace.

He cut 24 products down to 4 core products.  And he focused on that.  That’s exactly what needed to happen.
