Also, the "PC-losering problem" presented as one of the central examples in the original 'Worse is Better' really is an example of 'worse' -- the unix approach gives a modest reduction in kernel implementation complexity at the cost of every single userspace program either taking a complexity hit (retrying on EINTR) or being buggy in corner cases. This isn't just "less" or "simpler" -- it's actively accepting "worse" in order to get a basically functioning thing out the door sooner and maybe fix the most-annoying warts later. (Minimum Viable Product, anybody?)
