Haha, I actually breed and sell  the giant Madagascar hissing cockroaches you have in your picture. They grow to be about as big as your hand, and love HEB flour tortillas and hiss when they hear loud noises. Unfortunately, our current atmosphere only allows the bugs to grown so big. A herd of giant coaches taking over earth is unlikely because the exoskeleton could not hold a creature so big, it would collapse into itself.  Although they do a great job destroying printers if they escape. 

Do you think the IPad will be a piece of technology we end up just recreating in the future? Do you think it will make computers obsolete, or will it become the next computer, what do you think?
