Since I'm curious, which do you prefer as a low-profile analog control method for video games?
Note: "Trackpoint nub" refers to the mouse controller found on some thinkpads and the right stick of the New 3DS, and "Touchscreen analog stick" refers to the type used in some iOS/Android versions of 3D games such as the smartphone release of Final Fantasy III, where the zero position is wherever you tap, and dragging from there acts like moving an analog stick.
Redrafted this to specify that I meant for video games, despite using a computer as one of the examples--there are simply no good examples of it on a video game controller. I wouldn't even have included it if not for the New 3DS.
