The newer ones also have unique personalities and temperaments, as well as a longer more involved 'hatching' phase. The newer ones can also feel hot and cold, they MUST be fed to stay healthy and they can get (simulated) injuries, as well as the illnesses like the older Pleo's.
They are both as friendly as one another. The newer ones have voice recognition though, and more touch sensors.
