First Look courses are designed to give you a look into the current state of important software or technologies that are either due to be released or are in a state of flux. For example, a course like HTML5 First Look offers insight into the current state of a new HTML5 standard and what web developers and designers can expect from it in the future. This particular course offers a high-level description of the HTML5 specification in its current state, how it differs from HTML4, which features are currently supported in which browsers, and how the specification might be supported in the future. Other courses from the First Look series include Web Fonts First Look, Windows Phone 7 App Development First Look, and CSS3 First Look. First Look courses may also be periodically updated as new information becomes available, and might also be replaced with a full Essential Training course once the technology being covered is more fully developed.
