Nothing beats PCs - and, as was mentioned, yay for emulators. There aren't (fully working) emulators (yet) for Xbox One and PlayStation 4, not even for Xbox 360 and PlayStation 3, but one day, one day, oh, they'll come, they'll surely come, one way or another!
As for consoles-consoles, I love my PS2, PS3 and used to like my now RRoD'd Xbox 360, but my Wii was and is and will be gathering dust. It seems it was built for this specific purpose - not allowing the dust to settle on the shelf underneath it. There's no other explanation for its lack of good games.
Although I like PS4's games, I'm not buying one - yet. And the main reason ain't that it's bad, but simply that I can't afford it. It's got more exclusives that "talk" to me than Xbox One, though, with Uncharted, The Order and God of War coming, and most people seem to have forgotten Shadow of the Beast that I simply MUST play as a former Amiga fanatic.
