Or just maybe any improvement makes Flash usable on Linux without crashing the browser. People might actually start enabling Flash on Linux if that happens.
I don't find Flash crashing my browser on Linux too often, but it crashes itself pretty regularly.
Plus the older hardware I run Linux on can barely show a 288p Hulu video, with lots of stuttering, even though the machine can play videos twice that resolution flawlessly in any of the native video players.
I've used Chrome since it was available for Linux and I've never once had Flash take down the entire browser. In fact, I can't say I've ever had a Flash crash at all in Chrome. Funny enough it crashes rather frequently in Firefox (still doesn't crash the browser itself though...)
Right, it's obviously dependent on a lot of factors. Apple wouldn't even support it on the Iphone. For general users it may work well enough with the right environement, but I use Linux for development and I have little use for Flash compared to the relatively big impact that it has on system resources.
