"I've been using its predecessors for years and, broadly
speaking, OO3 is the most useful, widely compatible software ever.
You can run it on anything: Macs, PCs, Linux, Unix workstations. It
includes six full-blown applications: the Writer word processor,
Calc spreadsheet, Impress presentations program, Base database
program, Math equation editor, and Draw graphics program. And it
doesn't cost a penny.
"The most interesting development is improved installation on
the Mac. With previous versions you had to install a Unix windowing
environment, X11, a non-trivial and potentially frustrating
procedure that's an instant turnoff to many Macophiles. It also had
a nonstandard look and feel. Now you just download and install
OpenOffice and run it like any normal Mac application. If you own a
Mac, it's worth trying."
