PAF runs on Windows 8 desktop and laptop computers. I think it should run on Windows 8 tablets, but not on Windows RT tablets, which lack an x86-compatible CPU.
(That said, there is some software that will run on my 7" Android tablet that is really awkward to use because it is designed to be used on a larger screen and a keyboard. Whether that would be the case with PAF, I don't know. This where the input you have asked from users would be really helpful.)
