Here's a pointer to a new site from Richard Byrne, author of Free Technology for Teachers. Android 4 Schools will look at resources and reviews of apps (mostly free) for educatots with a focus on K-12 schools.

Though that focus is K-12, I wouldn't dismiss the site if you are in higher education (particularly if you prepare K-12 teachers!) as it promises to include some pedagogy too, and includes apps for teachers, students, and administrators.
