I was impressed by the USB ports on the MIST which aren't present on either the Minimig or the Replay board. Finding PS2 keyboards and mice isn't as easy these days as one would think.
PS/2 keyboards and mice are widely available everywhere for very cheap prices throughout the entire planet except for Africa, certain repressive Islamic countries in the middle east, North Korea, Burma and certain isolated islands out in the ocean. Which one of those places do you live?
