I did a similar thing because I was almost exclusively using my PS3 for Netflix, but my motivation was mainly because the AppleTV runs at ~6 watts and my "fat" PS3 runs about 170 watts at idle and we were always leaving the damn thing on. By my calculations, my Gen2 AppleTV paid for itself in electricity savings about 3 months ago. I keep it because it's my only way to play discs on my TV, but it's seldom used, and PSN's massive security blunder left a bad taste in my mouth.
