You're wasting more money on consoles than you would on a PC, this is my argument.
Consoles are convenient. You don't need to upgrade anything, don't have to worry about viruses, but to an educated computer user these things are second nature.
Why are so many people willing to spend 300+ dollars on a console and then 50+ dollars a game? Why not spend that money on upgrading your computer and buying/pirating games off of the internet. Consoles are not better for gaming, occasionally more popular, but consoles are becoming more and more like computers anyway, why bother?
As a personal bias, I believe that it's more comfortable to play most games on the computer anyway.
