I see...yes, in order for that to work, you need to download portable apps onto the USB from your own computer, or a computer that will let you. After that, of course, you can use it on any computer that hasn't denied access to the USB ports.

You could try publicly available computers, like at an internet cafe. You could probably get the portable apps suite downloaded and installed from there onto your USB, then you'd be good to go. The other thing I didn't mention: they have an auto-updater, so when a new version is out, it'll update it for you onto your USB.
