I bought a gaming laptop (Asus G75VX, not nearly as beastly as this one), during college. I went back to my parents' place for holidays and some weekends, and I wanted to be able to play games if I wanted while I was there. Plus I had something to bring with me to school when I occasionally needed to, although it was too big to be something you'd bring everyday and take notes in class with. Gaming laptop seemed like the best solution. After I graduated and moved away for good, I sold my laptop, built a desktop, and got a cheap tablet.
I'm not saying that this Origin laptop (and, to some extent, gaming laptops in general) aren't a niche product, and don't usually offer the best value. But there are people for whom gaming laptops really are the best option. I just get annoyed when every article about gaming laptops seems to feature people questioning why anyone would buy one, and often implying that anyone who does did so out of ignorance. There's no need to point out that you can build a more powerful desktop for less money, most people are perfectly aware. Luckily the comments here don't seem to have quite reached that point yet.
That's not to say that some people buying gaming laptops aren't sometimes clueless people who don't seem to understand the concept of value for money. After I bought my G75VX I spent some time on the Asus forum for fellow ROG laptop owners, and I swear there was a new thread everyday with someone talking about RAID0-ing SSDs, or upgrading to 32 GB RAM (for a laptop used only for gaming and casual use).
