Though I did hear that they chose an incompatible FPU and that no creative programming can make it work, which will drastically lower it's performance. But I can't confirm this.

Let's assume that Acube/A-Eon knew about the FPU problem. If so, then what would be the reason to choose it anyway? Are there no price worthy alternatives they could have used instead? Or did they reason that the FPU isn't that important?

Reading everyones comments in various sites I'm not really sure how important FPU is. Some says it's used for a lot of OS and software related stuff, others that it's only used in some games. Which is it?

According to the AmigaOS 4 developer "Cyborg", lack of FPU is a problem, they will fix it with emulation, it will be slow but they have a plan to eventually speed it up a lot with a JIT emulation. Sounds sensible. Maybe we can stop arguing now?

Stupid question: is it possible to let the second core stand in as an FPU?

@itix

Even as a dedicated software emulation core?
