但是PC-DOS是唯一在IBM PC硬件发售开始时就available的操作系统,其他的兼容操作系统最早也要晚6个月才上市 ...

价格是关键,因为DOS2.0出来是之后很长时间以后的事情,这个期间是没办法预装的,也就谈不上捆绑。
查了 ...

其实没有硬盘也是可以捆绑的,虽然不能预装.
比如这条1982年WSJ上IBM PC的广告

这玩意儿那么贵啊,82年的三千美元,估计还有税。

这算很便宜了好吧,在PC之前IBM最便宜的计算机是System/23 Datamaster, 得$10000

Software
PC-DOS 3.30 running on an IBM PC
Digital Research CP/M-86 Version 1.0 for the IBM PC
IBM initially announced intent to support multiple operating systems: CP/M-86, UCSD p-System,[63] and an in-house product called IBM PC DOS, developed by Microsoft.[64] [8] In practice, IBM's expectation and intent was for the market to primarily use PC-DOS,[65] CP/M-86 was not available for six months after the PC's release[66] and received extremely few orders once it was,[67] and p-System was also not available at release. PC DOS rapidly established itself as the standard OS for the PC and remained the standard for over a decade, with a variant being sold by Microsoft themselves as MS-DOS.
The PC included BASIC in ROM, a common feature of 1980s home computers. Its ROM BASIC supported the cassette tape interface, but PC DOS did not, limiting use of that interface to BASIC only.
PC DOS version 1.00 supported only 160 kB SSDD floppies, but version 1.1, which was released nine months after the PC's introduction, supported 160 kB SSDD and 320 kB DSDD floppies. Support for the slightly larger nine sector per track 180 kB and 360 kB formats was added in March 1983.
Third-party software support grew extremely quickly, and within a year the PC platform was supplied with a vast array of titles for any conceivable purpose

老兵帅客:知道微软dos当年是怎么赢的吗?一共四个竞争者,它的卖四十多美元,另外三个依次是一百多、两百多和四百多,于是它赢了。

当年微机好像得2000刀吧,40刀是不是够吃10顿麦当劳了。
