As a user, I prefer having the option to decide how sensitive and/or valuable the data on my phone is, what the circumstances of losing my phone are, and how long I'm willing to wait to get it back.
You were out of the country, without Internet access for a while, you have un-synced vacation photos and not much else on the phone, and there's a strong possibility you misplaced it? There's probably not a reason to ever wipe the phone.
You had secret company data on your phone, without a passcode, and it was ripped out of your hands? Can't wipe it fast enough.
While Apple should offer users advice, I wouldn't want them to ever take action (filing police reports, taking photos, etc.) without my explicit consent.
Maybe Samsung faced a failure less of engineering and more of creative marketing.
Possibly with a slick James Bond-like digital clock countdown!
