For Nintendo, graphics serve the gameplay. For most AAA developers, it's the other way around. I'd argue that if Nintendo were trying to compete graphically, the resource strain would greatly reduce the quality of the games they produce.
It's great you're having a good time, so don't let anyone say otherwise. I just expect more out of a brand new game console at this point. Especially for $300 + $70 pro controller + $70 games + crummy dock screen scratching issues + desyncing controllers.
