Console for sure, though I love my 3DS

Consoles more in the sense that more of the favorite games are on consoles but right now I'm playing more of my 3DS.

Much more in fact.

Normally consoles, but lately I play HH more. Phase maybe ...

Its all about the games, so I enjoy both equally. :)

Handhelds and PC. The Animal Crossing - FTL - combo is a really strong time waster for me currently.

Consoles, although my vita is changing that :P

Consoles.

Although Vita has vastly changed my perceptions of handhelds in the last year. Before it, I wouldn't even entertain the idea of a handheld (the last one I owned was a Gameboy Colour in ~ 2000).

I'd go to the lengths of buying some of the PSP games that Sony ported to PS2 (Syphon Filter; Ratchet & Clank) just because I wanted to play the games but couldn't imagine ever owning a handheld.

Now, that's changed a lot. There's actually things I much prefer playing on handhelds than home consoles.

And I'm expanding too. I'm planning on picking up a PSP before the end of this year (just have to decide which model to get); and I plan on buying a 3DS either over the holidays or early next year, too.

Games...
Wherever Japanese support goes, I will go. Which means I'll own a 3DS sooner rather than later

Consoles definitely.

Every handheld that I have owned before, have got a point where I simply didn't have more games that interest me and got bored, so the handheld (GBC, GBA, PSP) landed in a box collecting dust for half a year, year, or more.
I usually got back to it after that interval, but it happened every time, never had such a long break due to boredom with home consoles.

handhelds are convenient, but nothing beats a console/pc.
