I would put myself in that set, but it depends on what you want to use the fingerprint for whether it's a good idea.

I prefer things exactly as they are currently. I don't want my fingerprint reader to be able to unlock the keychain. However, I do use it for quickly unlocking a laptop who's keychain is already unlocked. I do this probably 10 to 15 times a day. If I had to type my long-ass password every single time, then I start to not want to lock the laptop if I'm only running to the bathroom or something, which is a very bad practice.
