Nice testing! I've done a TON of video compression and I agree that flash is cpu intensive, but I believe depending on the compression algorithm for mp4 (i.e. baseline, high, ultra, etc.) it can draw more power on the end user's device, but I think it's negligible when compared to flash. Side Note: HTML5 videos may not use alot of power for playback (gpu), but try video compression (cpu) on a mobile device...HA!
