I just installed Efficient Diary on my computer at home. I have always enjoyed keeping a journal, but my handwriting is awful and as I spend so much time at my computer anyway it seemed good to try an electronic version.
I have found this to be much nicer than a password-protected Word document. The interface is intuitive, and you can change the basic display if you wish. This also gives you the ability to add images, tables and other elements.
Because this is software dedicated to one purpose, there are features that you cannot have with a diary kept in any word processing software. You can manage your entries by hierarchical grouping if you wish and other unique features. I am looking forward to using this on a daily basis. For more information go here.
I must mention that I get a free license by posting this review here.
