By USB Apps i mean the platform, not actual portable applications. http://www.everythingusb.com/software.html I am starting to get interested in PortableApps Suite. It is freeware and simple. Can work with applications at www.portablefreeware.com so it has a huge selection of portable programs. Mojopac is automatically off my list because it does not work without admin rights which my school and most work places use. Ceedo is shareware and too much hassle for me using it. U3 is fine but only availlable in USB's purchased.
