Sun, DEC and SGI made the same mistakes imho; they ignored PCs for far too long. Apple too by the way. They thought people wanted custom hardware and software to render movie, run 3d software, do scientific computing etc and for a while that was very true (as someone who has many Sun, DEC and SGI machines still at home and they all still work perfectly, which you cannot say for PCs from that age, for me it is still true but alas), but PC hardware, software and economies of scale passed them by and they responded far too late. It went the same way with mainframes to minis, minis to workstations, home computers to pcs, so it was not like they did not have examples of this in their past. It was printing money in the 90s for them though, things were just too good.
