Judging from the ability to use a mac keyboard as a setting when installing Ubuntu and having a "Mac" section on the ubuntu forums, I would say that at least Ubuntu can be run on a Mac. I've never done it, though.
While passwords can be brute forced given enough time, your face is almost certainly available to someone who has access to get at your computer.
Also, you could say that face recognition is just as secure as writing a reasonably long password on your forehead. Someone takes a picture and boom. Access.
Personally, I refrain from writing my passwords on my forehead - regardless if I can see a suspicious-looking character taking a picture of me square-enough in the face to capture all the digits. And, I also refrain of using or buying face recognition devices...

I am ready, captain!
it's "Line-oox," right? haha, kidding.
Wow, I've been saying it wrong for two years...

I must say...I agree. I don't flip my desktops over while there's a disk inside. People just expect their systems to be as resilient as an N64. I once had a game that I found in a sewer in the school behind my house (I was an adventurous kid) and it worked and didn't damage the console. I cleaned the game obviously. But then again, I didn't turn my N64 on it's side either haha. Out of curiousity, can you turn a PS3 on it's side while a game is in there, spinning or not spinning? It looks like you could accomplish that feat with a Wii.
You owe me a new keyboard slashdot! Dx
You know what happens when someone is told NOT to laugh? I can picture it now...
PictureLady: No sir, no smiling.
Driver: *stiffles a chuckle*
PictureLady: Sir...
Maybe waiting two hours in a quiet room will remedy that however...By the way, at least in my state, you can call ahead. I was in and out in 30 minutes = record. Maybe that's why I have a big smile on mine....lol.
