Unlike Lightroom, Bento 3 leverages Apple’s Bonjour technology so you can now share your Bento libraries with up to five users over a wired or wireless local network. You can also encrypt any field and assign passwords to secure your information in Bento 3.
The new Grid view in Bento 3 delivers an innovative method of displaying thumbnails of photos, text and numeric-based information, while improved File Lists show image thumbnails, instead of just text.
Best yet, if you own Bento 1 or 2, upgrade pricing is only $29. It's hard to beat that price.
