The only thing that's changed is now some keyboards allow 12 or more keypresses at once over USB, where the limit used to be 6. The only legitimate reason to go with PS/2 was if you had to press a bunch of keys at once for a game or something that you had to use both hands on keyboard. USB is not faster, but it's not really slower either. It is easier to deal with, so there isn't much reason to get a ps/2 keyboard over USB.
