I guess PC but console-wise the newest thing I own is a PS3. Never really bothered with anything after that since nothing except the 3DS interests me. I'll probably end up picking one up eventually when I run out of DS/PSP games to play (so not for a while)
Out of the current consoles I own a WiiU which I play a ton and am trying to hack vWii (I would have if I weren't so lazy), an Original 3DS, and I am getting a Laptop which I plan to game on (mostly older stuff, lightweight games, and emulators).
I bought the PS4 shortly after launch, but I've not really touched it since I built a new gaming PC last year (i5-4460 3.4GHz, 16GB RAM, Radeon RX480 8GB GDDR5). I'm now keeping my PS4 on firmware 3.50 to see if any exploits appear.
My Wii U, New 3DS and Vita are of course all using the latest exploits.
I'd love an Xbox One but if I had that kind of money, I'd put it towards PC upgrades.
