I agree with the above with one caveat: maybe we have not yet seen the best way to implement a PIM interface. All we have are software analogs of real-life tools (rolodex, calendar, post-it notes, etc) because that's what we know and love. But what if someone scrapped that legacy and redesigned a PIM UI from scratch, and it blew away what we're used to? I'd be first on board, learning curve or no.

I must be masochistic though-- I'm forcing myself to use Office 2007 at home.
