I'm afraid to get OS4, since nearly all my components in my A4k/CSPPC depend on Mediator (I've sold my Zorro -cards long ago). OS4 would seem like downgrade currently compared to OS3.9BB2+WarpOS+AFA_OS+other patches, where I can use all my current software with all the PCI cards I have.
However, I might buy one for support.
