Out of most people I know I think I am at the top end of using new
technologies out of all of them, thus I have no reason not to think that in
general most people won't bother installing or know how to install special
software for J2K.

That sentance doesn't really make sense, but I don't understand how a 16-bit
image can be any better than an 8-bit image when displayed through 8-bit
DACs.  Please explain.

You're just scared of the figures.  You also seem incapable of answering
questions.  Please estimate what % of people will downgrade your image to
8-bit before viewing it.  I think it's quite high, what do you think?

Indeed, and I'm one of the "some".  However the benefit of a slightly
smaller file size (or slightly worse compression) is not enough to spend 10
times longer opening each image.  When people can view J2K images just as
quickly as normal JPEGs, there will be no problem.
