I wouldn't be surprised if that were the case. I have never known another Pokemon to be able to work as well with technology as Porygon can, but I think they can be at all different skill levels too, just like any other Pokemon.
I don't know if this would have anything to do with it, but perhaps it has to do with the fact that Zack has evolved, too? Zip is still at Porygon's first evolutionary stage...so maybe it could also be compared to Zack having a higher 'upgrade'.
