GIMP is a great product. I think it's quite unfair for people to say that it "sucks" on Macs and to complain it ignores conventions on Windows. It is *not* designed as a Mac or Windows program! It is a GTK program and will only feel at home on a GNOME desktop. The fact it has been successfully ported to other platforms and generally works extremely well if you can get used to having a program that's really at home on a GNOME desktop sitting in your Mac, Windows, KDE, etc desktop is great! This program can be a great *free* alternative to Corel Paint Shop Photo Pro or Adobe Photoshop for most users of those programs.
