&#62; Have you heard of MobileMe?<p>MobileMe is paid up front, and not ad supported.  There is no collection of private data for the purposes of targeting ads, and your actions are not correlated to your search history, or any website that uses AdSense or DoubleClick.  Your email may be on their servers, but it is not connected to a tangled net of tracking information that follows you everywhere that you go.  Maybe Apple could add these things, but their business model has been for the customer to pay for their service up front, not for them to find creative ways to monetize any personal information they might have.<p>They did recently purchase Quattro Wireless for mobile advertising, but they say this is to provide a framework for iPhone developers to include ads in their apps.  It's probably a competitive play to get developers to not use Google ads.
