Gary wants to know the difference between Evernote and DropBox. Leo says that DropBox is a great cloud-based file storage solution, and is great for photo backup as well. It's like a suitcase in the cloud that users can toss stuff into. Evernote syncs notes which could include photos and videos. Evernote has more structure, contains notes, to do lists, etc, and it's all searchable. They're complimentary, to be sure, but they are different.
Gary is also wondering about Bento. Leo says that Bento is a database program from Filemaker. Evernote has a better feature set and is free. Another great program is Catch, but it's more business-oriented now.
