spirantho,
The main reason there's not a great deal of OS4 programs out there is the coders are starved of hardware; give them OS4 on the classic and they can get started so when it's ready on the dedicated hardware there's much more software.
Correct me if I'm wrong, but isn't that what the AmigaOne was for- so developers could get started writing code for OS4? After all, the A1 was marketed as a "developer board".
