I also use a Palm, I use "Go Pix" software though -- seems to suit my working style best (sometimes detailed notes, sometimes very sketchy). I use multiple categories to keep track of each roll (they move from "unfiled" at first through "pending" and "processed" and "scanned" and then exported into the memo pad, then to my PC and I print the notes and include them in the binder with the negative pages themselves for further printing/filing -- with a separator, I don't trust storing my negs (even in sleeves) DIRECTLY in contact with office laser paper)

My gopix logs contain body/lens/date/strobe/exposure/title info per entry, and a name for the collection/session/roll. I include a date stamp in the roll names too, and often add some notes during development and/or printing
