Steve will continue

Apple on January 5, released a press statement, as Letter from Apple CEO Steve Jobs about Steve Jobs' health, despite of "obvious distaste for talking publicly" about it. Steve says,

... As many of you know, I have been losing weight throughout 2008. The reason has been a mystery to me and my doctors.

... my doctors think they have found the cause—a hormone imbalance that has been “robbing” me of the proteins my body needs to be healthy. Sophisticated blood tests have confirmed this diagnosis.

But, just like I didn’t lose this much weight and body mass in a week or a month, my doctors expect it will take me until late this Spring to regain it. I will continue as Apple’s CEO during my recovery.
