For my personal stand on this matter, i'd say there is just about absolute NO good reason to purchase a console over a PC.
The fact is, low cost PCs nowadays running GPU-optimised setups or APUs can perform equally if not better in games compared to a console. A PC also functions as a platform where you can do work, surf the net, download music, participate in forum communities, discuss about porn and more, whereas Consoles are more or less strictly limited to games.
Even for the argument for 'family friendly' and 'couch gaming' is completely invalid in 2016, because there is nothing stopping you from using something like Chromecast to mirror your digital output onto your TV, and you can plug in any matter of wireless controllers as you desire to use on your couch or bed provided you have the appropriate slots on your computer - which can be solved by using expansion hubs anyway.
For those that talk about console exclusive games - use your brain for a second, how many games are there on a PC that are not available on a console? You can also use a PC to run virtual machines or emulators. Games also cost an exorbitant amount on consoles, you have to pay to use the internet [PSN,Xbox Live] and pay full price upwards of 40-80USD nowadays for AAA titles. On the other hand, the PC platform is no stranger to insane sales - most notably Steam, at multiple times throughout the year. Piracy is of course an option for both platforms, but that requires you to burn the image onto a disc for consoles - oh, and you probably need a PC to download said pirated product in the first place anyway ¯\_(ツ)_/¯
I haven't even brushed on the done-to-death topic of performance on PC vs Consoles because it is strictly not needed. PC wins hands down, it is also a modular platform that you can choose to upgrade at any time to suit your needs, whereas consoles are one-dimensional and once they feel incapable you need a complete replacement. To be fair, Sony and Microsoft do go to a great length to ensure that newly released games will run on these dated hardware. Look at games like Watch Dogs for example, severely downgraded from it's original graphical fidelity in order to make it accessible to the Playstation 4 at acceptable performance.
As for ease of use, is a console that much easier than a PC? While i agree that initially setting up a PC may be a daunting task for the less-able, once everything is up and running you literally
1) Press the Power button on your case
2) Wait
3) Double Click/Search whatever game you desire and run it
You don't even have to build a PC yourself, you can head down to your local BestBuy or something and grab a computer that already has everything fitted together and Windows installed. Hence i don't see any argument for 'ease of use' either.
Did i miss out anything?
