There's also Bokura ga ita ("We were there"), Suzuka, Lovely Complex, Nomade Cantabile... there are a few "unrealistic" humor spots here and there, but they seem to just be for further- detailing a character's emotions, dreams/daydreams or reaction to an event in a scene.
Also, though they're not anime, live action shows such as Long Vacation and Nodame Cantabile are very good too for their realistic life circumstances.
