Missed the point
@Kevin Whitefoot: I think you are missing the point. This is the easiest way to backup your data for the millions of people that have NEVER backed up in their life and in the case of the Traveler, it could be used for sales people who like to think they are tech savvy but don't know the first thing about computers. Plug this bad boy in, and then put it in your wallet. If your laptop gets stolen, or is comprimised in any way, then all is not lost.
@ Anonymous Coward: I would not trust net backup ever. Do you really think you have any more control over anything that you post to the web? Backing up at home, I totally agree, and the clickfree hard drives are good for that too. I use one for my home network. Captures data from my wife's pc, my pc & laptop and my kids pcs and they never have to lift a finger.
