Some good points above
In my very limited experience with the G1000 I found myself furiously chasing the numbers on the tape. Normally if my heading, altitude, airspeed or power setting are not quite right, I just make subtle adjustments and wait for them settle to where I want them.
Also found in the circuit that I had my head inside the cockpit too much, searching for info instead of keeping a proper lookout. Presumably that becomes less of an issue when you become more familiar with the equipment.
