Ok, I send a letter to Individual Computers about my poll. Here it is:
Dear Individual Computers,
I think I'm speaking for many of the Amiga community when I say I've long missed high-end expansion cards for the classic Amiga platform. I did this poll to check if I was right, and I was:
Is there any possibility that you could consider making a new 060 or 060/PPC card for A1200 (or A3000/A4000)? You could for example make a kickstart project out of it. As you can see in the poll, there are many people out there who would like to run AmigaOS 4.1 on their favorite machine.
