A Kindle Fire is not a computer. If it is so is an iPad, or even a smartphone.
Of course both those things are computers. Dibble has a degree in computer science and I'm a recent college dropout who was studying for a degree in computer science, so that counts as like 0.2 of a degree.
I'll throw another log on the fire that those things are in fact computers. As is your DVR, NAT router, parts of your car.....huh...other things.
But I think he was meaning PC when he said computer the first time (seemed kind of clear too)....we're just nitpicking here.
