So you can have all the benefits of flash authoring, without the drawbacks (killing your customer's batteries).

How true is the battery thing today, really?

Objectively, on my relatively powerful workstation PC, watching Flash videos using Flash widgets on web sites doesn't tend to bump either CPU or GPU frequencies up noticeably.

In contrast, watching HTML5 video can cause either or both to go way up, with consequent extra power consumption, temperature rises, fan noise, etc. And all these trendy modern animations and canvas/SVG effects in browsers that are replacing some of what Flash used to be used for apparently require more effort from that workstation-class hardware than literally doing full-screen real-time 3D rendering in a graphics application.

Of course it's possible that this is just dodgy graphics drivers -- I do have an extremely low opinion of AMD's supposedly premium products since I've actually used some of them -- but those same dodgy drivers are there when using Flash too, and it can still play videos without raising the ambient room temperate by multiple degrees.

Well hardware decoding of flash video has improved over the years, but I can tell you that while I can play 1080p hi def videos without seeing much bump in my CPU (on the laptop), when my aluminum macbook pro is freezing cold to put on my lap in the winter, nothing warms it up as fast as playing a random youtube video with Flash.
