I have been using a few Portable Apps for quite some time now on a non-U3 512MB PNY memory stick. I travel with this and use it, generally, on Administrator restricted computers. Mostly I use Portable Firefox, and Portable VLC Media Player. I have read a lot about U3 and heard a lot about it on many radio shows bu I cannot figure out for the life of me what it is all about and what it offers that I do not have now withe the Portable Apps I now use, or plan to install in the future.
I am reasonably computer literate, though certainly not an expert. Perhaps I am more of an idiot than I though, but can someone please post a bit more info (maybe a basic FAQ) on what U3 is and what it has to offer over what I already have? I would greatly appreciate it.
