Considering I don't get a lot of time to play my console, since the main TV is almost always being used, any other free time I have is usually spent on the computer or playing handhelds. I don't really go out much, so I spend most of my time on handhelds at home.

Well if you can count the games I play on my Windows Phone than I would say the majority of my playtime is away from home.

While I do play my handhelds mostly in my home compared to outside, I definitely use its portability to my advantage. I'm rarely playing my handheld on the same couch that I play my consoles on. I'm usually on my bed, or at the table, or somewhere else. :P

mostly when i go on duty outside my hometown.

I get motion sickness, so no hope trying to play handhelds on the move for me.

Ironically, I play my PSP more when I'm at home. The only time I play it away from home is when I'm waiting for a movie to start at the cinema.

I bought the DS to play the games that came out for it, usually at home. I rarely play on the go.

At home. always at home.

At home and because of the overall flexibility like you mentioned.

While:

On the toilet.

Watching sports.

Watching movies.

At home.

On the go and at work I just use my Smart Phone.
