I like it. We can argue over & over, but we need *something* and I think
this does a good job of reassuring LaTeX users, welcoming new users,
and introducing the most important concept in the first paragraph.
My one remaining gripe is the first sentence. IMO, saying "Linux" in the
first paragraph will immediately make SGI, HP, IBM, and other workstation
UNIX users suspect that it doesn't work on their platform. Why not "for
UNIX?". Or "UNIX and other systems" to include OS/2 and the experimental
Win32 port. In fact, I would argue that you could just say "LyX is an open
source document processor." in the first sentence. That way, you're
stressing the most important point by making it the only thing in the
sentence. the only reason *not* to do that is that the subheading says
exactly that. Well, OK, do we need the subheading?
