Obviously Steve is a smart guy and I want him to lead Apple. He often does things that piss me off; however the good he does for Apple and my "user experience" completely out-weighs the bad.
He is a public figure who tries to keep his personal life private. When you are a public figure and you are not transparent people will speculate. In fact I often feel that he tries and puts a spin on everything that is communicated about him (ie he or someone is trying to control the image). This magnifies the analysis and speculation related to all communication that comes from Jobs and Apple.
In the end like everyone else I wish him the best if he is seriously sick and I hope he recovers quickly. This from someone with three immediate family members recovering from cancer. Don't forget how difficult these health issues are for his wife and kids.
