Dude#1 - My new MAC is supposed to have voice recognition to let me log in, but it's a total piece of crap and it never works.

Dude#1 - Did you check out that Volvo demonstration with automatic brakes that are supposed to stop you from having a collision? It crashed in front of everyone!

Dude#2 - Yeah, that's a total unvention.
