Well, what I forgot to mention (but kinda hinted at) was that "Personal Computer" quickly became used to just mean business PCs and not Home Computers (even though it technically applies to both). When the IBM PC came out, it and the legion of clones took over the business PC market and replaced the S-100 CP/M market almost overnight. So when "PC" is just used to refer to business PCs and the IBM-compatible DOS/x86 platform completely and thoroughly dominates the business PC market... than naturally the term "PC" will come to be synonymous with that platform.
