It looks like the A1200 is the computer that gets a lot of attention. When I go to a web site it seems to be the one that gets posted as a picture.
What do you think?
When you add FPGA cards any amiga will just be the keyboard and perhaps some interfaces, the rest will run on the cards. So it is a matter of taste and preferences what model you want to use. In this sense A600 is no different than A1200.
