Of course it's in men's interest to keep women subordinate so they can be more easily exploited (and it would be in women's interest to do the same to men (...)).
I fail to see why - what has this to do with gender? Does your statement still make sense if we replace "men" or "women" with "people"? Do you believe that men are women are natural enemies?
1. Is astronomy scientific?
2. Are celestial maps scientific?
I bet the latter questions would get significantly less positive answers.
This has to do with discrimination: paying someone less than someone else for the same work simply because of the color of their skin.
Unproved assumption. The same fallacy often occurs, when non-caucasian people are discriminated against. I bet the the same thing would have happened, if the employee would have come from a Eastern European country. It's not about race, it's about money.
Most people want to have the opportunity to hand off their device for whatever reason, even if it's "hey, look at these pictures of my cats."
In ten years, this will sound as absurd as the predictions in 1950's that we would communicate in the future by having robots deliver us letters from each other. When the number of wearable computer users reach a critical mass and the technology is sufficiently advanced, there's absolutely no need to hand over a mobile device - content can be transferred to another device nearby so easily that the process will seem almost telepathic.
