Review for CardBook by BurkoJames
Rated 4 out of 5 stars
Most of my collegues use Outlook, so having a vCard-compliant address book works well, allowing me to send contact info and vice versa. The ability to add secondary emails to contacts directly, without copy/paste is also great. A current lack of documentation however hurts its role as a power user upgrade.
