I don't mean this to be sexist, but on the topic of why they have girls showing off electronics. Most girls seem innately able to stand in front of something in an introductory fashion and still look natural. Guys, on the other hand, always stand there a totally unnatural straight armed gesture that looks like he is both blatantly posing and it also unfairly makes him appear like a dufus.

Just an observation from most pictures or displays I've seen.

With great power comes Awesome irresponsibility.
