Yes, but using Emumaster as an example, the Amiga emulator is almost unusable because games expect an Amiga to have a keyboard. It is a TODO in the official site, but the developer's recommended solution in the meantime is... wait for it... "use a bluetooth keyboard" :P

re: Bluetooth keyboards: I'm making a note to go and test one I've seen for the iPad, very, very small. Too bad they don't have a trackpoint or a trackpad...
