Regarding the comparison page, I think it is worth noting Diptrace, a Windows based schematic capture and pcb layout tool.  It is generally Easy to use (easier and more intuitive than Eagle) and creating new parts is a breeze.

It's greatest strength is that it includes a standard library with 100,000+ parts and is constantly growing.  You can suggest parts that they presumably have a team constantly adding.

Their interface isn't glossy or cross platform nor do they have built in SPICE or simulation tools (although one can export for such) and no 3D.  But their part library is unrivaled and hopefully Fritzing can try and match it.

Thanks.  We'll have a look.
