But MS-DOS and Win16 isn't software anyone still have to deal with when making new content because the software isn't used by anyone to deal with any content, only legacy software that won't hurt anyone. It's isolated. But a browser doesn't get stuck in time like a OS does when it dies, they don't surf on the same Web as when they were popular while an old outdated OS still runs its old outdated software just fine. MS-DOS and Win16 also weren't garbage, IE6 is.
