I don't think the issue here is that Jobs looks frail while Ballmer looks like he's been eating for two. People aren't buying tens of millions of iPhones out of pity. Apple has made its recent success off developing and marketing products that consumers want to buy and that make them happy to use (look at how many people by an iPod or iPhone and go on to become Mac owners.) Microsoft mostly makes it way off of enterprise sales and bundling with PCs. That's fine, but it doesn't tend to lead to a culture that creates products that end consumers get really juiced about.
