I believe it does size properly to intrinsic size of an image in  
Safari 2, but I could be wrong. In any case, you can expect the  
official Safari 3 release to be more like current nightlies than like  
the beta.

I think the HTML5 recommendation will be to use <audio> and <video>  
for audio and video when possible. These provide for fallback content.  
Apple also has a proposal in the works for selecting one of several  
media items for <audio>/<video> based on accessibility considerations.

<embed> is there primarily for content handled by plugins. The best  
plugin markup for degrading gracefully in a wide variety of browsers  
nests <embed> in <object>, and it would be unfortunate to make such  
markup non-conforming, even if you can use <object> alone to target  
newer browsers only.

Maciej
