Equal, maybe leaning towards handheld. Whenever there is a PS4 vita game that supports cross save I find myself playing it constantly while switching back and forth. The best is when you're playing on the TV but you have to poop lol, no reason to stop playing! The thing that annoyed me the most above the Wii U is that the range didn't extend to my bathroom even though it's only 15 feet away.
Probably console most of the time. But then again I do like laying in bed playing games, something I miss with the Wii U after moving to a new place and the TV being too far from the bedroom for it to work.
I'll likely split the difference between the two. Even with a 3DS I play at home something like 98% of the time, the other 2% potentially being when I'm on vacation and everyone else is asleep. Honestly, I have no idea how it will work out with a three year old and twins most likely arriving in March, but the bathroom idea holds much more weight these days. We all joked about that with the Wii U, but I can hardly hold a consistent connection with my Wii U now from my couch six feet away. Though that might have to do with a three year old dropping/throwing the controller a time or two.
I might just get a second AC adapter or dock to keep the thing charged out of sight and just dock it at night when everyone else is sleeping.
In bed, in a different room than the TV. So I guess that counts as portable. That said, apart from taking it on a trip or to a friend's house, I doubt it will leave the immediate area. So that makes me think more "console."
I voted portable, because it will be undocked way more often than docked. Maybe that should have been the poll: Docked vs. Undocked. Because I may play it, as I did the Wii U, in my living room while my wife is watching some TV show or something. A lot.
