Right now I use PowerMail for email, AddressBook and iCal for time and people and Kinkless GTD for projects. They don't integrate well.

I just hired a part-time assistant to "help out around the computer" and I am trying to figure out how to share information with her, and perhaps in the bargin, get my own applications to talk to eachother better.

One thought is to use something like Daylite to organize my life, and coordinate her tasks with mine. Any thoughts about how well this works?

If I move to Daylite, should I also move to Apple Mail? Will Apple Mail "melt down" at some point? Does it handle lots of emails comfortably (it didn't seem to at OS X 10.1, the last time I tried it)?

Once I switch to Daylite, will I throw kGTD in the trash, or do they complement each other?

Should I get two licences for Daylite, or should I get her a .mac account and share addresses thru Address Book sharing?

I know this is a mishmash of questions, but I have a mishmash of confusion in my mind.

TIA
