For the last year its my 360. Nothing was released and I just use the Netflix/Hulu on my Wii U. My Wii U was gathering alot of dust from February to August, but once Pikmin/Earthbound came out its pretty much been my main console. I was even one of the 15 people that bought COD Ghosts on it.

All of my home consoles, because I never move them. Also, my DS.

My PS3 collected dust because I really only used it for the exclusives or the Final Fantasy/Metal Gear franchises. When there wasn't an exclusive that interested me, it went ignored aside from its media capabilities.

Wii gathered dust between big exclusives, too.

Both of them were necessary components to my entertainment center and worth having just for the knowledge that I could play any game from anybody at any time but there were definitely droughts.

*edit*  Oh, and the DS.  I actually own SIX DS consoles but the last two were for my daughter.  To be honest, in 2009 I switched to PSP and never looked back.  three phats and a white lite are all sitting in a box in my cabinet gathering dust at the moment.  My daughter has a pink Lite and a DSi and they still get use, though--and this makes no sense she she has a 3DS and it can play those games!  She carries those two, a PSP, a 3DS, an iPod and a Nexus 7 everywhere she goes.  

I got a 3DS and went back for the games I ignored, though.

Wii and DS. Good consoles with some good games, just never got round to playing most of them.

I don't play my PSP anymore either and never really owned that many games for it.

vita collected a bit of metaphorical dust when the PS+ wasnt that good. recently though ive been loving soul sacrifice, better than I thought it would be.

your offerings (spells/weapons/powers) are only consumed within quests (unless you break them with over useage) so you dont have to worry about farming more for the next quest. Also when you start a quest, you are seconds away from the boss and the fight is in one arena so you dont have to spend an age getting to and following the monster around unlike monster hunter.

still want to play tearaway and vita version of LBP.

Ever since I beat Pokemon X in October my 3DS has been turned on maybe once. I'm actually thinking of trying Animal Crossing since it seems like an addictive game that may make me see past my hate towards the 3DS's hardware. Other than that my PS3, PS4, Wii U, and Vita all see regular use.

Among wii, wii U, 3DS, and PS3, PS3 is in the dust, since 2 months after i bought it(and sing PSN+).
I turn on once in a month to get the free games from PSN+.

360 at times.
I probably spent about 20% of my 7th gen gaming on that and 80% on Wii.

None of my 7th gen systems - Wii, PS3 or DS - ever collected dust during last gen. Plenty of great games to play.

Presently, between my VC library and its GC compatibility I still play my Wii once and a while and although I haven't played a game on my PS3 since Bioshock Infinite, I'm always watching movies and TV shows on it, both discs and files I've saved on the HDD. My 3DS gets plenty of attention and my WiiU is currently my system of choice (at least since August).

I guess I can conclude by saying my DS has been put away for a while now, but that's it.

The Wii and its plethora of plastic peripherals is the king of all dust collectors.

My Atari 7800 doesn't collect as much dust as the Wii does.
