OpenOffice looks right at home on Windows, which honestly is the platform it's targeted at... although you'd think they could update its appearance to at least look like XP.
I won't buy any version of office X. I forked over $225 for Office 2001 at the badass academic price when I was in college because I'm a badass motherfucker. I wanted to go to Redmond and ram a 25' pole up Bill's ass because 2001 isn't carbon. FUCKING FAGGOTS. But it works just fine in Classic, especially in Panther now that classic is PERFECTLY SEAMLESS.
I've got Orifice 2001 and Appleworks 6, which works for me. For about 99% of the things I type, TextEdit is the app of choice for me.
if I really wanted offence X, I'd bust out with some gnutella action, but then, I'd probably enjoy a bath in hot acid or lava more.
