Click to Flash is the ideal middle ground for mobile devices. Only load the Flash when the user explicitly requests. 90% of the time, the user won't notice the Flash missing, the other 10% it is available on request. That solves the issues of 1) Flash in the background draining the battery or exploiting security holes and 2) the annoying advertisements.
It's great to have Flash there when you need it. So many sites still have integral Flash content.
