Define runs well. My macbook is silent until I visit a site with a flash banner at which point the cpu fan comes on. That tells me that flash does something computationally intensive even when displaying what looks like a 4 frame movie with a button that prompts me to click to the next destination. The time between loading a page and hearing the CPU fan come on depends on how ad-laden the page is. While my machine doesn't lag and Chrome Canary will occasionally lag a little when scrolling those pages the first time, I'd have to say that translates to high cpu utilization which would kill a phone's battery pretty quickly. The other problem was focus - most flash games used the mouse pointer for directional control. The mouse pointer doesn't exist on a phone and a tap would correspond to a mouse click. Redesigning Flash to deal with those issues on web pages where HTML5 solves many of those issues convinced Adobe to concentrate on Air, and leave webapps to HTML5. Flash won't disappear overnight, but, new development ceased. Whether they make it support GPUs before relegating it to a 'security release only' update policy is hard to say. Personally, I have removed flash from my macbook and only Chrome/Chrome Canary(my primary browser) can even see Flash enabled pages/sites. Months ago it was very irritating when the version of flash bundled with Canary would crash on one page and violate the sandbox causing google.com/music to crash as well. *still amazed at the irony of using Flash for google.com/music :)
