Don't look now, but consoles have been continuously updated for the past 6 years in order to make them as identical as possible to PCs. Consoles are no longer "for the sole purpose of playing games". They aren't really that much cheaper than a PC these days either. The line is becoming thin, and PC is more popular than ever for the gamer who wants it all.
Let me rephrase that—the sole reason one would get a console over a PC is to play games. I mean, even TVs can do media streaming now, so why would you want a console for that purpose. Consoles, at least at the time of release, are cheaper than a gaming PC, so they have more mass market appeal. Sure, it's no secret that the most hardcore of hardcore gamers use a gaming PC, but that's only because they have $1.5k to spend on one. Most people who want to game prefer something that is cheap yet still powerful, hence the popularity of the PS4 and XB1.
