http://www.silentpcreview.com/SuperTale ... Virtual_PC -- A USB 3.0 device with 4-channels of flash memory & 32mb cache for near-SSD performance, combined with Ceedo, which can replicate your own PC on any other PC without admin rights.

Mike:

I can see how this could be incredibly useful. One thing I couldn't figure out from the Ceedo site is how the system would run without telling the BIOS to boot from the USB port. If it includes a small version of WIndows on the drive, how does it boot into the system?

My description was a little misleading. It's not really a copy of your own PC but a unique operating environment of its own that's customized with all of your own settings, presumably taken from your main PC. Check our the video that was linked. It's pretty informative.
