I have always been concerned about backing up my laptop because most of what I do is on my laptop. I tried various medias such as DVD's, network back-up onto the server etc, but this little drive solved all my backup problems. It's simple, silent, light-weight, nice looking, easy to use, affordable and reliable - I couldn't ask for anything more. I will probably buy another one since it's light-weight to use as extra storage. As it's USB based, I can easily add many more of these little devils.
I am not too satisfied with only 1 year warranty though - they should provide at least 2 years warranty!
