Aren't brute force tricks don't quite work nowadays since phones and other security measures don't allow multiple incorrect password in a short amount of time? How many incorrect tries do we get before the phone counts down before you can enter a pin again?

If you need a watch then go for the iPad, if you need a device with larger screen, go for the Apple Watch.

Pros: It's a small phone.

Cons: Bad battery life due to it being small.
