I'll agree with you that the A1 is a flop at the current time, simply because it's not readily available. (Its owners certainly seem pleased with it, though 8-)).
However, OS4 is already an awesome achievement - as is, and the final version is due by year's end. Here's hoping that new hardware (such as Troika's Amy) also materializes soon. Obviously, that will be key to OS4's future.
Btw, all the best on AROS. Very cool project.
