Quote from SereniusI've never really understood portable gaming unless you spend a lot of time riding buses/trains, or have to spend a lot of time in airport lobbies. I used to see some guys from ES who would walk around with a DS or PSP plastered to their face constantly. Seems a little too hardcore.
It's also great for recreation and relaxation. I often play the DS in my bed before i go to sleep. Other people read a book.
