I have used a sizeable (2200 cu in) Jansport backpack and an Eagle Creek laptop sleeve for the last four years. I need to carry a change of clothes, books, various odds and ends (cellphone, palm pilot, etc.) and a 15" laptop on a 20 mile round trip bike commute. The combo has worked well for me. I keep a medium sized garbage bag stuffed in one of the backpack pockets for rainy days. When it is wet, I put everything in the garbage bag and then into my backpack. My only gripe with this combo is that the Jansport does not have a waist belt. This would be nice for some extra stability.
Here at New Mexico State University, the first circuits class including a mandatory laboratory has been taught in the freshman year (calculus I is the co-requisite) for five years. This really does wonders in keeping the student's interest level up. The students must also do a group project with a final report and presentation at the end of the semester.
