Also, my daughter has a Nintendo DSi and my nephew (who lives a couple houses up the street) has a Vita and Windows Phone, and though I occasionally will check out games when they want me to, I'm never really that interested in them.
Over the last year I've had a couple of chances to buy used XBOX 360's and PS3's from friends and co-workers, but have passed on it. Mainly because there's not many console games I want to play now-a-days, and if there are, they're usually released for the PC as well (the last big name games I played were Borderlands 2, Dead Space 2 and FEAR 3) - so I don't really see the point in getting a console.
I should also say that I've become VERY spoiled with the AppStore's games and prices, and with so many great games available so insanely cheap, it's hard to convince myself that getting a Vita, 3DS or even a big console would be worth it when even at used game pricing, I could pick up 10 times the games for the same price in the AppStore.
Anyway... sorry for the lengthy response. But yes... I know there aren't many of us, but my iPod/iPad is my main portable gaming device, as well as my main ALL-AROUND gaming device, and I have no intentions of that changing any time soon. =oP
