OK, thanks, so programs don't have to be in the registry to run? My dad was trying to explain this to me but I was kind of confused. He said most programs when installed, write in the registry, so it'd be possible on the initial computer I install them on, but on subsequent computers they probably wouldn't run? Also he said that I might experience some lag in the computer accessing the USB key...does anyone do this regularly, good or bad experience?

So it won't work unless it's installed on the actual computer? What if I just want to make sure I always have my notes and table images, would that work from the usb key as long as the software was installed on the computer as well?
