Best PDA for College?

andyic3 asks: "College starts in a month. I've been searching for a very simple, tiny, modern PDA for storing due dates on. I've looked at the REX 6000, but it's too simple. I've looked at PocketPC's, but can't seem to find anything smaller than the old iPaq H1910. I've looked at Palm solutions, but can't find anything there. What's the best PDA for this application?"
