Asian Surveying and Mapping have a post that outlines the practical differences between aerial photography and satellite imagery. It’s a good primer on the subject, and can help you determine which of the two technologies is best suited to your application.
In a similar educational theme, GIS Lounge have a post that talks all about scale, an important characteristic of data that is oft-overlooked by the new wave of non-traditional spatial users.
