I'm still looking for a contacts App for the iPad and came across dejaOffice. It looks like just what I want, but I don't think it will sync with a Macbook.
My wife and I each have an iPhone, Macbook and iPads. It would be nice to sync all together with a good contacts and Calendar App.
As I stated in another post, I would like to be able to search the "Note" field of the contacts to find out info.
