“Ich bin hin- und hergerissen vom PL3, meine Frau murmelt allerdings bereits etwas wie „nach jahrelangen Kämpfen habe ich Dich von den wochenendlichen Computersessions weg und jetzt spielst Du stundenlang mit Deiner Aquariumelektronik“.
Nein wirklich, die Möglichkeiten mit dem PL3 sind phantastisch und die Usability ist so großartig, dass es richtig Spass macht, sich immer tollere Sachen einfallen zu lassen.”
