Charles,

A very good answer. I have not found the learning curve on KiCad to be that steep, nor the re-learning curve either -- I tend to do a couple of boards, and then have many months before touching it again, but picking it back up has not been hard. However, I have not used FreePCB; it sounds like, from your description, that it must be significantly easier / more intuitive to use.
