To many people these days, computers are synonymous with laptops. They have limited need for portability or, if they need portability, a couple of hundred grams does not mean much to them. As for battery life, it is possible to get PCs that will run for a full day without charging. Yeah, that is not as good as two days. On the other hand, it's not necessarily meaningful. People who travel a lot or do a lot of field work may need it, but it won't be a primary concern for most.

I'm still trying to figure out the reproductive organ bit. It sounds like an issue for people who use their computer in awfully unergonomic postures, particularly since most computers radiate heat towards the back rather than the front.
