I think that it's a very "neat" widget. I have earth desk on my Macbook Pro (5th), and enjoy it as well; however, the wi-fi (which is necessary to have a real-time view of the earth, is poor in the particular building I am in at school. Wallify will help to animate my screen, thereby helping time slip by faster. I'm giving it a positive review as I personally have had no issues with software conflicts. Hey, try it, it's free. The full version isn't but 1.99, and that's not required to have. Don't care for it much? Uninstall it. I hope this helps someone.
