That's like a topless Vegas show girl asking, "I'm a professional dancer - how do I explain I am not a stripper?!?"

Yes they both are attractive women that get topless on stage for money. Either you have a distinction that those two things are different or you don't. It's not an easy thing to explain (I know it's a bad example).

The best way to show off it's competing power is to actually compute, write some code, then compile it on the device. HELLO WORLD!
