Jobs started in a garage to build Apple computers. He was healthy.

Apple tried to take on IBM. He was healthy but got nowhere.

Apple had the education business with IBM servers(shearson called Jobs). He was healthy, but more high schools used PCs.

Apple introduced iPod. He was healthy, and more music was sold to iPods; Apple got a commission. Foxconn( parent Honfujin precision industry) used slave labor(15 hour work day) in china to make iPod.

Apple abandoned IBM powerPC and went with intel. He was healthy. But business was just so so.

Apple introduced iPhone(bigger iPod). iPhone(AT&T subscription purchase) is a big success, but Jobs less healthy.

Apple introduced smaller iPhone. He is doing weight loss, too. Perhaps worrying what else Apple can introduce after smaller iPhone; perhaps mainframe design(embedded server) instead of PC in iPhone? Take on IBM(this time on service in cloud computing) again, you need to be lean and mean?
