The lights are on
Its rather simple, just get him a PS3. Like you said its not high maintenance like the 360 and it offers wifi, bigger storage space, free online play, internet browser, and a blu-ray player. Also it offers 1080p resolution if you use a HDMI cable. The only notable games that you will miss out on with the 360 is dead rising, gears of war 1&2, and left 4 dead 1&2. However you will gain Demon's souls, Uncharted 1&2, and Killzone 2.
So I say just go for the PS3, they will be getting netflix at some point in the future.
