This is what I found on my laptop when I got the fingerprint reader working: The scanner was surprisingly low-resolution (92x62px), and nothing like the "5000ppi super secure" scanner I was expecting... The driver would get a scan from the reader and the driver passed that scan on to whatever was asking for a scan. Not so secure.
Regardless fingerprints are really bad for security because they can be detached from the finger or recreated from things you touch. They are probably slightly better than nothing, but with such low resolution, I suspect that if we let 100 random people try to unlock my laptop with their finger... someone would get in... but I could be wrong.

The suitability of an authentication scheme is entirely dependent on the requirements of the problem one is trying to solve. For identifying a fast food worker at a cash register, they are (functionally, not legally or morally) a good fit for the problem, because they are hard for a coworker to replicate, and not likely to lose. For applications in which you need to protect against high skilled attackers, they're not as great.
