Both (or all three, if we're counting PCs too), but if I had to choose one I'd say I slightly favor handhelds. My 3DS probably gets the most play, followed by my PC and PS3 tied at second and my 360 third.
I'm getting a Vita for Christmas, so that will probably also sit with the PC and PS3 as my second most used gaming device. Seriously $180 for a Vita plus The Walking Dead, Uncharted and Sly Cooper? Yes, please! That's less than I paid for my 3DS alone. I was going to pick up a Wii U this Christmas but I couldn't pass up that Vita bundle at that price.
