Non-linear video editing is even more so, I feel. I do not do a whole lot of it, but I've discovered that there really is no halfway decent free option (besides iMovie, but that's only 'free' if you bought a mac, and it's incredibly weak)

I don't really do video editing myself, but depending on what level of complexity you need, some of my friends/acquaintances use one or more of: PiTiVi, Kdenlive, LiVES, and Cinerella. Of those, Cinerella is probably the most 'serious' (and also has the highest learning curve).
