I foresee more devices being 'hacked' via pin codes being simple and/or written down than by someone lifting a finger print.
How secure is secure enough? The weak spot is, and always will be, the human aspect.

Same goes for the Android swipe pattern system except that if you turn off the pattern display it is much more difficult to detect since length and pattern can vary. However, on two separate occasions people have noted to me that they "now know my pattern" despite my being fairly fast and subtle with how I entered it.
All things considered, I think finger prints are much more secure for most people.
You've always (or at least back to the iphone 3gs) been able to choose to use a more complex PIN.
Personally I wish the pattern-based lock screen was more dynamic. Like if it rotated while you entered and had a random starting position, it'd make it much harder to read either real-time or through smudges. And it'd be more fun to boot.
