I stopped waiting around for OS4 about the time that it nothing had been done on it for 6 months one week before its planned release.
TBH I felt like it was an utter slap in the face. The final straw however was when I saw the production A1. Sorry, it may have been a better machine than the prototype with the slot connector, but to me it seemed like a cheep imotation and lacked any kind of inovation.
I bought a pc and have been running BeOS happily ever since. Amiga inc had their chance, they blew it and that was the end of it, nothing I've seen since convinces me otherwise.
Pegasos is a nice machine I suppose but unless BeOS could run on it (the ppc veriaty) then I see no reason in buying one.
(Morphos may be a nice system, it seemed it when I played with a demo of it on a mates ppc equiped A1200, but it simply doesn't do what I want of it).
Now I await Zeta - BeOS r6. It should be out by xmas or shortly their after.
