The first PC I specced (in 1985) was for an IBM XT PC (XT indicating that it came with a hard drive, rather than two floppy drives). The standard disk was a wopping 5MB - I had it upgraded to 10MB (the cost was prohibitive).
When one of the senior directors wanted to know whether it was sufficient, my answer was that we would not be able to fill it in our lifetimes (given that floppies were 256KB and the operating system (DOS 1) plus all the programs (Multimate, Lotus-123, Harvard Graphics) took up less than 2MB). Lotus-123 spreadsheets typically ran below 10KB, as did Multimate files, so yeah - plenty of storage.
And the whole system cost about 10% more than an entry-level 5-series BMW, so EXPENSIVE!
