As most people, i'm also trying to find a nice alternative for Altium that would be suitable for hobby and commercial use.
As i'm still a poor student, I've narrowed down the search to Kicad and gEDA.
Tried Kicad, didn't like it at all, especially that the left mouse button doesn't do anything useful (like select a component).
So i'm asking: is geda better in terms of usability? I'm currently running Windows, but I could install Ubuntu, no problem.
I'm not scared of complexity, I just want something that won't poke my nerves.
