A calendar within the desktop manager, similar to what Palm has with theirs. I know, I know - Outlook, google calendar, etc. None of them do what my old Palm calendar did - let me have a multitude of color-coded entries on the same calendar. Different colors for work vs. home vs. personal vs. notes like birthdays, etc.
Secondly, a modification to Where's My Phone or a similar program that will turn on my GPS so the phone can be located if its lost/stolen. I don't like having GPS on all the time (battery life, privacy issues) but would like the ability to remotely activate the feature if necessary.
