I received the Palm Tungsten E2 about two and a half years ago as a going off to college gift and it is one of the most helpful organizers I own. I initially wanted the organizer because I found it hard to carry around and use a bulky campus planner. This PDA is small, lightweight and offers 4 easy push buttons at the bottom for the calendar, contact information, tasks and notes--all the things I needed easy access to as a student. It's even easy to upload and download information to and from my Microsoft Outlook which is more convenient when I have access to my computer. Just write everything I need for the day on Outlook, shoot it over to my PDA and I'm ready for the day.
There is also an alert for tasks and calendars that you can set to either sound off or pop up as soon as you turn on the screen. My only complaint for this product is that I never hear the alarms. Other than that, it's great, I can customize my screen, store pictures and music, important dates, assignments and events, and play games. I would highly recommend this product for a busy student.
