- The point I was making is that Windows has device independence. This allows
- it to support lots of different video cards, and take advantage of video
- coprocessors if available. It also allows it to support lots of different
- sound cards, dumb and intelligent printers, etc., all through a single API.
- AmigaOS doesn't have this, because originally there was no need for it, as
- there was only one Amiga hardware standard. But now AmigaOS is in dire need
- of device independence.

- Your article has proved NOTHING about what you say. We seem to agree that
- AmigaOS and Windows have different, although overlapping, sets of features.
- Yet you believe that AmigaOS's feature set is somehow "better" overall, while
- I say that the two serve different markets and cannot be compared.

- : Alright. If it replaces everything, THEN WHY DO YOU NEED MS-DOS?

- There are two reasons. First, DOS is necessary because people still want to
- run DOS commands and applications. Second, Microsoft would much rather sell
- two products per PC than one.
