Yes, just because certain types of game (e.g. casual, card-based, social, anything designed for 15-minute short bursts) lend themselves better to a handheld. Others (epic/cinematic games, certain RPGs, FPSes, local multiplayer) are better suited to a home console or PC.
The market that goes for handheld is not necessarily the same market that goes for home consoles, even if there is some overlap.
