Apparently there has been some concern as to the performance of Flash 10.1 on Android devices (specifically the Nexus One). Two videos have surfaced recently that have raised some questions as to Flash's ability to handle responsiveness on games, and overall battery performance on both games and streaming video. One of the videos in question showed a Nexus One, with the leaked HTC Desire ROM, running FarmVille and displaying a lack of sensitivity to touch. The other video demonstrated the use of several games and streaming video over an eight minute span, noting a 25% decrease in battery power in that short time.
Adobe caught wind of these videos and posted a response on their Flash Mobile blog. They made mention of the fact that the Nexus One with the leaked HTC Desire ROM was running an alpha version of Flash Lite and not Flash 10.1, thereby explaining the issues with the game. Additionally, to show that Flash can be utilized without killing your battery, Mark Doherty of Adobe posted a video on Vimeo showing a Nexus One playing a 17 minute streaming video from the YouTube website, and then showing a mere 6% decrease in power over that time. He also states that the "tests show that video can be played for well over 3Hours over WIFI from youtube".
