I am clearly a fan of it. Like the videos of it so far, and have high hopes.. but lets be honest.... is it really more secure?
Think about it. Security is only as strong as the weakest link. Samsung bragged at the release event that it will keep parents out of their kids phones (not in my house... I pay the bill, I get in whenever I want, or they lose their phone!)... and it keeps the other kids out of your kids phones. OK, but does it. As I understand it, you will be required to have fingerprint and password backups... so if the password is the weakest security, then how is the iris scan more secure? So long as a weaker option is available you are still only as secure as that.
Let me put it another way... a solid steel door, with 3 deadbolt locks, bio-metric access... is no more secure than a $30 storm door, if it has a glass window in it.
