Leopard running on an Atom Processor
Using PC_efi technology (a means to run OS X on a PC without kernel modification), an anonymous source for netkas.org has managed to run and benchmark Leopard on an Atom chip, which is rumored (and denied) to be headed for Mac.
The Atom Processor would certainly make a good candidate for a mini-tablet. It's small enough to fit any form factor, and low power enough to run for long periods in small devices. According to netkas, you can even run one of these on solar power. Here are the results of an Xbench test, courtesy of netkas:
