I assure you, the fact that you see it as a computer has nothing to do with wether a court will consider it a computer. Your belief that since you can run applications on it makes it a computer would open up so many Noncomputers to your definition of computer,like would a Furbi be a computer, or a leapfrog learning device?? And I doubt a court will ever go that far though who knows what the future will bring. Maybe in the future it will, but clearly this conversation isn't about the future, it is about the present.
Also, what do you mean when you say that "though what you do while using the connection can get you in trouble"?
