Based on my gaming habits, I am definitely a portable gamer. I mostly use my Nintendo handhelds & PSP (not the Vita), depending on the game I am playing---usually the most advanced system for the game I am playing on (e.g. DS Lite for GBA games, 3DS for 3DS & DS games, Switch for Switch games, etc.).

I like to move positions when playing games (and in general), and being locked into a monitor (and thus locked in one position) does not appeal to me in the long-term. For example, I sometimes like playing games on my bed or couch, while standing up, or walk in place/short distance. Despite this, I do not like to play games in public. I see gaming as an exercise of being immersed in the experience without (too much) background noise, and opposed to filling time whilst practicing reality (with excess noise).
