I'm a strange one... I've got a 360, PS3, Wii, and a nice gaming PC.
My gaming PC is on one side of the living room with 2 monitors (27" and 23") but the third monitor is the 40" Samsung LED TV on the other side of the room. I have a 25 foot HDMI cable in these runner sheath things across the ceiling over to the TV.
I will sometimes play PC games on the TV that way, using a wireless XBox 360 controller (silver) for Windows. I played Bioshock Infinite this way, for instance. And Max Payne 3. I've also done some Need for Speed that way... and most of my Skyrim playing that way.
If it's something I want to use mouse/keyboard for like Counter-Strike, or StarCraft 2, or Diablo 3, I'll play it on the primary monitor (27") instead.
My consoles largely collect dust, but then again so does my massive Steam library... I don't game as much as I just aimlessly surf the net.
I did recently play The Last of Us on the PS3 quite religiously until I completed it. That was great. Last time the 360 really saw much use was Halo 4 I guess. It's mostly those exclusives that cause the consoles to get fired up. If I have the option to play something on PC, I usually will. The TV method with controller is always available these days, and tends to work very well. And it looks better to play PC Skyrim at high resolution with high res texture pack, and all the bells and whistles my GeForce 670 GTX can handle, on the TV - than it would to play the PS3 or 360 version of Skyrim.
That said, after a long period of my PC games working reliably, I'm now having random system reboots while playing a lot of stuff... really annoying. Tried to play some Witcher 2 yesterday and was getting crashes after like 20 minutes. Not looking forward to troubleshooting this, especially if it culminates in an expensive part needing to be replaced.
So those are the moments that I appreciate the simplicity and relative reliability of console gaming.
My Wii has hardly seen any use... just a couple games of Mario Kart, and a vague intention to finally eventually finish Wind Waker and Twilight Princess, and Skyward Sword (for some reason none of the post-OOT Zeldas have grabbed me and kept me coming back the way it did, other than maybe Majora's Mask)
