I don't want to play games on a tiny, low res 3DS screen.
Hardcore gamers still exist! ...... hardcore gamers like high end hardware (hardware is decent you say, what other portable games console has better?), proper control scheme (3DS frankenstick says two sticks is important) and full on console games experience on the move (why should I accept diluted games experiences just because I am using a portable).
I support innovation of course, but I like two sticks for control as a foundation (give options for others), high end graphics and full on, high level games.
