You could argue that this is at least partly the fault of Flash
developers who are entirely incapable of writing well-optimised code.

An example of the kind of thing that unnecessarily eats up CPU due
to bad code would be an ill-advised use of an ENTER_FRAME event, which
might get dispatched, for example, 40 times per second if that is
the SWF's framerate.

I [1] have got flash blockers installed in all my browsers on the intel
machines, as a Flash advert running in the background will ramp the
processors up to 100% with the fans running up high temps. That "isn't"
working well.

With the flash block in place then I can just enable the flash to work
on the few pages it is really neccessary, YouTube & Vimeo video pages.

Well I don't see it crashing the browser too often- never in iPlayer for
example, and in Youtube just occasionally, in Firefox, after going from
full screen back to small window. Doesn't seem to do it in Safari, but I
don't use it as much as Firefox, so I don't know.

Mmmmm. Apart from the battery issue, none of that appears insurmountable
if somebody actually took the trouble to make it work. Oh well...

In the mean time I shall continue to use Flash, as HTML5 is no good on
my iG5, and when I get an InteliMac (that is, when my bad capacitor
batch iG5 finally goes phut) I'll have another look at HTML5.

Plus one data point here. I can't remember what the site is (maybe a TV
listing page) but on my wife's machine (sans flash-blocker) there are
animated Flash ads writhing above, below and on both sides of the main
content. It makes my skin crawl.

Might it be here? <http://www.tvguide.co.uk/>

That's the one I tend to use and, as you say, it's a wee bit Flash heavy to
no actual use.
