Here's the interesting thing: all of my machines have autorun disabled, have since that became a "feature". And U3's loader still loads. I don't get it, but I haven't had time to take it apart and see what makes it tick.

It also autoloads, as I said, on my Susi machine. None of the apps work, obviously, but what ever U3 is using, it isn't dependent on the computer's OS so much. And that's kinda scary, actually, becuase it really does act like an embedded OS. Fortunately, U3 has an option where you can disable it's urge to load when slid into a USB port.

And since that was developed with SanDisk (among others), and the zaptag being a SanDisk product, there is some interesting (good and bad way) potentials with it. Assuming that there is ever a need for them.
