These vids aren't pointless because they're making much more money through YouTube clicks and whatever they might sell, than a few Watches are worth. I don't like calling these "tests" though, it's just clickbait and I wish MacRumors wouldn't give them free advertising.
So they're not stupid because someone makes a lot of money from them? Sorry, but thats pointless for me. These pointless "test" videos add as much value as the kardashians do on TV. They are stupid entertainment for people with nothing better to do.
