This is just to provide a data point some may find useful.  I also sit
in the  'java annoys me' camp, but I have found examples of applets
that do scientifically useful stuff in a reasonably portable manner
with Java, and which to my knowledge simply can't be done any other
way.  I think this site can be used as a good tester for what SAGE
could expect to impose on its users if it went with Java:

http://phet.colorado.edu/web-pages/simulations-base.html

These are physics applets, running out-of-browser, and can give a
reasonable measure of startup times, portability, performance and
complexity for things that do a fair amount of mathematics (though
none does specifically 3d plotting).  The physics in there is
accurately computed, so the computational load isn't completely
trivial.

Cheers,
