All of my current gen systems, since that is what I assume you wan to focus on, are Wii, 360, PS3, DS, PSP, gaming PC. Of all those systems, I don't really know if I have a favorite. My main console is probably the 360, but I wouldn't say I like it more than any of the others. I just tend to buy the multiplatform games on it since most of my friends have xbox's and that is where most of my online play is had.

All of the systems from all generations, Wii U, PC, Wii, 360, PS3, DS, PSP, xbox, gamecube, ps2, gba sp, psone, sega saturn, N64, sega genesis, sega 32x, sega nomad, sega cd. Had an old Nintendo, but it broke a very long time ago...

In my house exist the following machines where games are played (with Wii U being the latest)

Wii - Stopped being used after getting Wii U but otherwise was used by my kids to play Wii Sports Resort or one of the Dora The Explorer games

X360 - Least used "home console" system, last used for playing first two campaign chapters of Halo 4. Before that I think it was for Skyrim and Minecraft.

PS3 - Most used game system in the history of game systems for me. Used it weekly... especially with the PS+ titles and 1 hour trials... just lots of games.

3DS - Mostly used for games that have Mario in it like Mario 3D Land, NSMB-2, Paper Mario, Mario Kart... lots of Mario. Also used for Art Academy and Crosswords Plus. Looking forward to Fire Emblem - Awakening

PS-Vita (x2) - Used mostly for Smart As and Playstation All-Stars Battle Royale. Two machines and two copies of each of those games. One is mine, other is belong to wife.

Sony Vaio Z-Series laptop with Windows 7. Used to play Battlefield 3 (Origin), Age of Empires Online (Games for Windows Live), and a number of games on Steam.

iPhone - Last game I played on there was Rayman Jungle Run (like Rayman Origins only simplified for iPhone controls)

Kindle Fire HD -  Used mainly by kids to play whatever free educational type fun/distraction game wife downloads.

Mac OS X - I guess closest thing to a game on that has been some Facebook web-browser Flash based game.

...

Wii U is getting nearly daily use by all 4 members of my family. This leaves machines other than 3DS and PS-Vita untouched since Nov 18th.

You play AOE Online? If you play Sparta you should ad me. I'm actually playing it right now and always looking for someone to play 2v2. I'm " The_Splitcrow "

I never give away my consoles.i Used to be a nintendo fanboy now i love everything. So i have a N64, Gamecube, PS2, DS, 3DS Wii, PS3, Xbox 360 and now a Wii U. Planning to get all next-gen platforms

Systems currently used: 3DS, PS2, and Wii U.

I have a PS3 but usually only use it for original Playstation games and Bluray movies. The last actual PS3 game I played for it was Assassin's Creed Revelations.

Oh yeah, for Nintendo systems, I also owned a Wii, DS, GBA, SNES, NES, and Gameboy.

Other systems included MSM, Mega Drive, Dreamcast, PSP (which I pretty much only played one game on since the first year), and PSX.

well right now i have 2 ps3's and a 360 and i might trade my 360 in towards the wii u. i dont use the 360 all but once a month its not even hooked up to the tv.

forgot to list recent handhelds as well, DS Lite, 3DS(stolen), 3DS XL, and PSP(1 stolen, 1 left).

Wii, 360 and PSPGo. Sold my 360 for a Wii U, and my PSP is starting to show its age.

And forgot to add that the Wii was my favorite and most used console last gen. Tenchu, Arc Rise, Silent Hill, Xenoblade, Last Story, No More Heroes, Resident Evil 4. These are the games, along with Goldeneye that occupied alot of my time. Surprisingly only 1st party title I really love is Smash Bros which ive lost days to.
