What do you like best?
I like that it is easy to sit down at the computer, open iMovie, and create a completed project in a couple hours' time. The learning curve is very small, as the program is very user friendly.
What do you dislike?
I dislike that the click-and-drag function is less than ideal. iMovie does not always allow you to drag your media into the creation space from, for example, a computer desktop. Additionally, as with other apple products, apple does not always provide solutions for common, known issues online. It is often more helpful to search forum posts in order to solve a recurring problem.
Recommendations to others considering the product
If you have a Macintosh computer, this application should be your first attempt in movie or slideshow creation.
What business problems are you solving with the product? What benefits have you realized?
iMovie is a great, free (for macs) option that allows anyone to create a movie production. You can add music from an audio file and pictures from an event to quickly create a slideshow. If you want to add more detail, you may--simply click on a given picture in the slideshow and edit the number of seconds it will be shown, how it enters and exits the screen, and so on.
