In the near future? No. Intel can provide that service at a fraction of the cost compared to Apple. However, I do think eventually (5+ years) more Apple "computers" will be like similar to the iPad and will likely use an Apple-designed ARM processor. (There's a big difference between designed and built.)
Apple knows the future is efficient, low power and thin computing devices. The current crop of X86 processors are designed to be multipurpose and are highly inefficient (and overkill to some extent) for most consumer's needs (internet surfing, word processing, video playback, etc).
We're going to see big changes in the desktop and notebook space in the next five years (think trucks).
Microsoft is banking on this idea also (see their ARM announcement).
