I think this may be of more interest to those who want something more secure than Windows. There are already a number of live linux distributions, some of which have a persistence feature. This means that you can write your data and settings to the USB stick without troubling the hard disk. I don't use this facility, but I have Mepis 11 on a stick with more applications than I will ever use - and I don't run it as root.

Looks like this is too little, too late - unless it has features not disclosed in what I've read about it.
