That Samsung ad has been wildly successful and has been running for a very long time. It only comes across "badly" to existing iOS nuts.
I won't speak to the marketing copy here. I agree it certainly doesn't move me, but then I'm (and no doubt you're) hardly in the target demographic either.
I've never been overly fond of Samsung or Moto ads and I'm a long time Android User, Android App Developer and also mod the ASOP for fun and customization.
Then again, I'm probably not their target audience either since I won't go for anything not a Nexus device and dislike preachy advertising for any brand.
