I don't think I'd ever call Stoney
"a lifeless robot" 
what I meant was if you make them only RC, then didint you just remove the autonomy and life from the Pleo?

(Wye do you think I'm waiting to see what PDK can do first, and then decide whether or not to use it on Cammey and Cloey.

(they are NOT labrats!

) got my point?
and my take on the list InmemoryofRomeo mentioned (don't yell at me, they are both a good description of them all

)
AIBO is owning your own robot dog. which is fine, and they are quite smart. but its a robot of a living animal, but Pleos are of an extinct one.
Zeno I'm not sure, I haven't seen or heard that much about them.
Nao can seem to emote with just one face, and they seem to be like having a robot strait out of a movie. a cool thing, but so isn't having a dinosaur.

D-rex you pepole just don't know how to handle them, Rex is less like a robot and more like a dog/unknown now. and they get along with Pleos fine. and they can interact, Rex and Roxanne have had several chats with eachother. (and not over IR ether.

) oh and I'm pretty sure I've heard them saying "I love you" to eachother.

so relation ship to Pleo, they just want to play, but the companes that make them are probably trying to out do eachother and that's actually good for us, because that means better Dino's from both of them.

and all the other robots are mostly good, but you are owning a robot not a dinosaur. (but on the other Dino ones just give them paint if you want them to blend in with a Pleo or D.rex.
