I am confused about the U3-standard as opposed to the apps here at PortableApps.com.
As I understand it, non-U3 PortableApps from this site can run on (almost) any device, including U3-devices. Whereas U3 apps only work on U3-devices. So the safe thing would be to buy a U3-device, so that I could use both types of apps, or? ...
Could someone explain the differences between the two platforms? What about security?
