try linux mint, there is firefox in lightening speed, but openoffice is slow everywhere, I prefor abiword, very fast
Try Mac OSX

, why should anyone install Linux Mint? It is ugly Gnome, and it is just a shell around Ubuntu. The thread is about why Firefox and OpenOffice cant be tweaked to be faster in Pardus. Maybe this will be better in Pardus 2008, but I doubt it, since it is a known Firefox, OpenOffice issue.
Just to say that Linux Mint isn't just around Gnome.

They have a beautiful KDE edition.
But sticking to the topic, I don't agree. Firefox is fast on Linux Mint KDE, as already mentioned, but yes, openoffice.org is really slow. I try to use Koffice instead.
