Has anybody used this before? In case you haven't heard of it before I'll give you a quick down and dirty: Its an application that combines Mail, iCal, and Address Book into one application (sort of). It lists all of your contacts, emails, and calendar items in one window and can sort them by date, contact, etc. etc.

I was wondering if anybody uses this and if they do how have they integrated it into their lives. It seems sort of neat but I can't decide if it would be worth my time fiddling with it to figure it out.
