I haven't touched a console in almost 10 years. Ever since I got my first 3D accelerator card for PC (Voodoo Banshee). That was back in 1998. Last console I owned was PS1. No point really, once you have a dedicated gaming PC machine, it is easy to expand its capabilities to match and/or surpass the tech level of whatever console that comes along. Movies & media? Dedicated player box, or even a decent media-PC box will always beat whatever capabilities a console can give. Especially in terms of customization and expandability. Most games that come out for consoles, come out for the PC as well. Again, PC ports always have more customization vs. their console versions. As for games for which there are no PC ports, usually these games are console-only for a reason. (kiddie crayola games, with few exceptions thanks to their publishers for mostly marketing reasons) Also, there are emulators. Sooner or later (usually much later), every console is reverse engineered and an emulator pops up. Nearly half PS2 games are already playable on an emulator (providing you have a powerful & modern machine), and within a short period of time the rest will be as well. If you care about console games that is. (I don't.) By the time PS4 rolls around, there will be a working emulator for PS3.
Seriously, if someone is over the legal age, I don’t see a reason why that someone should own a console. Unless that someone is some kind of a eccentric billionaire who still likes to play with his cho-cho trains. I mean, if you have the technical know-how to put together a gaming PC from the ground up, why do you want a console your 8 year old neighbor plays with?
