I remember there were plenty of iPADD jokes when the iPad first came out. I'm fairly certain there is a LCARS-interface app for the device as well.

I am the author of the LCARS Reader iPad app and have been bullied by CBS many times. Their own general council however admits to having no legal basis for their claims.
What CBS does have is expensive lawyers that usually get their way.
Unlike George Lucas, who makes people license the word "droid".
