Chris Lilley responded to this already.

I've had similar sentiments. The Opera SMIL implementation seems 
fine, but I really need the scripting. SMIL is so darn friendly and 
easy that I underwent a couple of months of seeing just how much 
JavaScript I could eliminate -- I was pleasantly surprised. I miss it 
in Firefox.

SMIL is more machine independent since you don't have to calibrate 
your setTimeout loops and your delta-x's and delta-y's and so forth 
for machines with differing horsepower, but I have done some 
comparisons which suggest (at least in ASV) the JavaScript animations 
run a bit faster and smoother. See 
http://srufaculty.sru.edu/david.dailey/svg/svg_filter_play.htm for 
some experiments. (Apologies in advance that I haven't tried to get 
any of these to work in Firefox yet.)

Certain kinds of animation like bouncing billiard balls around a 
table are, I think, beyond the scope of SMIL, but it is fun to think 
about future languages for declarative animation which might be a bit 
more dynamic than SMIL is currently. I suspect the folks who came up 
with SMIL are thinking fun thoughts since the entire philosophy is 
quite compelling.
