Ideas for organization and reminders online for a student transitioning to college

Hi Everyone!
I am supporting a student who is transitioning to college in a few months. I was asked to find a way to improve his note taking and organization for that transition. The team is interested in a PDA or itouch something similar. Due to cost etc..., I am interested in finding online solutions or already accessible solutions first. I have a few ideas such as using Google gadgets and one note etc. Any other great sites or things out there for a college bound child with executive functioning difficulties?

THANK YOU!
