This software integrates with iCal and the Mac OS X Agenda to complement them and offer better control and power to the stored data. All this with a really refined interface, that makes the input of the data as well as it visualization much easier.
Moreover, Bento is a complete project manager that even allows us to share the projects on the Internet with another five users.
As if this weren't enough, the way it exports the data has also been implemented perfectly, so that synchronizing data with other software or, simply, making backups is much easier.
In its effort to integrate with the system, Bento also allows us to use the photos that we have in iPhoto to send emails with photos, and make them even nicer with the different templates that it includes.
