I don't think its worth redoing MS Office in FB (although, hey, I'm sure
it would be better!). We need some new killer apps.
Here's my suggestions for some killer applications (although I doubt
whether they are *that* killing)

Quicktime Editor - the ability to draw on each frame of a Quicktime
Movie as well as usual video editting functions of cutting and splicing

Scheduler - timetable scheduler or planner - input tasks to be done,
resources required for tasks and resource availability and let the Mac
juggle it and/or show up the conflicts.

Timesheet database - data entry for time recording against
tasks/projects collected into a database for time spent on projects

Anybody else with some good ideas they are prepared to share with the
group?
