OpenSUSE is another great linux distribution. I have ran both OpenSUSE and Ubuntu and currently have OpenSUSE on a live boot USB drive to tinker around on. Yes openoffice (which comes with the linux distros) is nice, and free, but you must know that not all software you know and love will work. For me, itunes is the deal breaker. Yes amarok and banshee are great music applications, but synchronization with my iPhone is not possible. Linux is great, and like previously said, runs very very fast and is not as susceptible to virus attacks (because so few people use it). But have fun if something ever goes haywire. I think no matter what you're running, the key is to be very diligent in backing up files stored locally on your hard drive. A 50 dollar external hard drive has saved my bacon more than once...
