I-schools
I-Schools tend to be interdisciplinary schools with students from a multiplicity of backgrounds including those related information, technology, and the social sciences. Depending on your view of on the Philosophy of Science, this either represents an intolerable pollution of the pure scientific methods used by a particular domain, or a fortuitious and logical combination of methods when analyzing a situation from multiple contexts (often, some form of social science and technology).

My personal background is in psychology, and as previously mentioned, I chose the field of Information Science and Technology based on a variety of factors, including personal interest in the field of technology, but also due to the relative flexibility in career options after graduation.

It may be disheartening to new students to hear, but Ph.Ds do not necessarily increase the average salary after graduation, particularly for individuals in the technology field. Generally speaking, the American Psychological Association reports that for individuals holding degrees in Psychology, salaries are significantly higher for individuals holding Ph.Ds. Eventual salary is certainly not the only factor that should influence a person's decision to consider an advanced degree, but it is nonetheless one aspect of education one should consider. IST is certainly  not hesitant about mentioning to undergrads that their undergraduate degree program has one of the highest median starting salaries in the University. This is no doubt in part due to the relationship IST has built with a number of major corporations including IBM, Dell, and others that recruit undergraduate interns from Penn State's IST department. In fact, if you're planning to go into academia, your starting salary as an Assistant Professor may be less than the median starting salary for one of the undergraduates (but not, fortunately, if you go into the private sector).

The APA in general has a good website intended for graduate students in psychology, but with some general relevance for all graduate students.

Here are some videos from different information science programs.
