- THE FUTURE
-
- The following sections discuss future releases of OS/2 and Windows and predicts
- which operating environments will be most popular. We expect Windows’
- popularity to grow over the next two or three years, especially for price
- sensitive markets. OS/2 should eventually become the standard in large
- business. However, we believe MS-DOS will continue to be the most popular
- operating environment for PC compatibles in all markets for the next few years.
-
-
- OS/2 2.0—Designed for the 80386
-
- Overview of OS/2 2.0. IBM and Microsoft are working hard on a version of OS/2
- that will take advantage of the 80386 processor (the current version of OS/2
- was written for the 80286 processor). We expect IBM/Microsoft to begin
- shipping OS/2 2.0, or whatever it is named, in 2H90.
-
- OS/2 2.0 is written for the 80386 processor and will only run on 80386
- machines. However, Microsoft officials have stated many times that the 32-bit
- features of OS/2 will appear incrementally, and that the initial release will
- not be completely rewritten to use the 386 processor’s 32-bit architecture.
-
- Microsoft has indicated that existing OS/2 1.2 applications will run under OS/2
- 2.0 without change. However, to take full advantage of OS/2 2.0, developers
- will have to rework their application to some degree. Depending on the nature
- of the application, the amount of rework could be significant.
-
- Enhancements to OS/2 2.0. Since OS/2 2.0 has not yet been officially
- announced, we cannot be certain what features it will have. However, we expect
- OS/2 2.0 provide the following advantages over OS/2 1.2:
-
- • Faster performance. Supporting 32-bit registers and addressing will add
- speed improvements.
-
- • Run multiple DOS applications. OS/2 2.0 will have the ability to run as many
- as 16 DOS applications in separate 640 KB virtual machines. These DOS
- compatibility boxes can be multitasked, and they will have protection between
- them and OS/2 native applications. This is in contrast to the current
- compatibility box which can only run one DOS application at a time and if that
- application crashes the whole system is frozen.
-
- • Better Windows compatibility. It is speculated that Windows applications
- will be able to run better under OS/2 2.0. It is unclear what this will mean.
- It could mean that Microsoft will provide tools to let developers port Windows
- applications over to OS/2. Or it could mean that Windows 3.0 applications can
- run under OS/2 in a 16 MB compatibility box, rather than the current 640 KB
- compatibility box.
-
- • Support for segments up to 4 GB. Applications written for OS/2 1.2 can only
- allocate a block of memory up to 64 KB in length. Performance suffers when
- applications deal with memory blocks that occupy multiple segments because the
- program must contain special code that hops between segments. An OS/2 2.0
- application could allocate a block of memory up to 4 GB, thereby improving
- performance.
-
- • Improved device driver support. More device drivers should be available by
- the time OS/2 2.0 ships.
-
- Look and feel similar to Windows 3.0. We expect that OS/2 2.0 will have a look
- and feel similar to Windows 3.0 (see below). Therefore, it will be much more
- appealing visually.
-
-
- Windows 3.0—A Major Step Forward
-
- Windows 3.0 is a huge improvement over the current Windows 2.1. We expect
- Windows 3.0 to be available in 2Q90. Competitive Analysis has written a ROM on
- Windows 3.0, which describes its features in detail. Here is a brief overview
- of its enhancements.
-
- Supports up to 16 MB of memory. Windows 3.0 gives applications direct access
- to up to 16 MB of memory when running on 286- or 386-based machines. This will
- allow much larger and more functionally rich programs to run under Windows.
-
- Visually appealing. Windows 3.0 has one of the most attractive interfaces on
- the market. It has a 3D effect and very good-looking color icons.
-
- Graphical file manager. Windows 3.0 offers a graphical File Manager which
- provides direct manipulation. The File Manager looks and works similar to the
- one in OS/2 1.2. This is a huge improvement over Windows’ current file manager
- which does not provide direct manipulation; however, it is still inferior to
- the Macintosh Finder.
-
-
- Which Environment Will Win?
-
- Various operating environments will probably be popular on PC compatibles in
- the future. In contrast to the past, when DOS was the standard for all PC
- compatibles, we expect different environments to be popular to different
- customers.
-
- Windows’ popularity will grow for two years. We think that Windows 3.0 will be
- successful to small business, higher education, and home customers. Windows'
- popularity has grown over the past year. And Windows 3.0 should accelerate
- that growth. We believe that, for business customers, Windows 3.0 will be the
- dominant graphical operating environment through 1991.
-
- However, in 1992, Presentation Manager should become more popular than Windows
- for PC compatibles selling to large businesses as hardware prices decrease and
- as new OS/2 applications appear. OS/2 should eventually become more successful
- than Windows (at least in large businesses) because it offers features—such as
- multithreading, advanced IPC mechanisms, and long filenames—that are difficult,
- if not impossible, to add to DOS.
-
- OS/2 will eventually become the standard in large business. Looking out to
- 1992, OS/2 will probably have its greatest penetration in large corporations.
- OS/2 Extended Edition requires expensive hardware and so will probably find its
- greatest acceptance in large IBM shops, since they are not too price sensitive
- and since they require communications between PCs and hosts. However, since
- both Standard Edition and Extended Edition of OS/2 require high-end hardware,
- they will probably not sell well to price sensitive customers (such as K-12 and
- home) for the next few years.
-
- MS-DOS will dominate for years. MS-DOS will probably continue to be most
- popular operating system for PC compatibles across all users for the next
- couple of years, especially to price sensitive customers.
-
- Following is a chart that attempts to depict the relative popularity of these
- three environments in 1992:
-
- This chart shows that we expect MS-DOS to remain the most popular PC compatible
- environment in 1992.
-
- The PC compatible market is fragmenting. Operating environments for PC
- compatibles are proliferating (DOS, various versions of Windows, OS/2 Standard
- Edition, and OS/2 Extended Edition). The PC compatible market is fragmenting,
- with consumers and education running DOS applications on 8086 machines, small
- businesses running Windows applications on 80286 machines, and large businesses
- running OS/2 applications on 80386-based systems.
-
- Macintosh is a stable environment. The uncertainty about which operating
- environment will become the standard has left PC compatible users and
- developers confused. They aren't sure where to commit their resources. We
- believe that some customers are delaying purchases until they know what
- environment will be successful in the long run. Apple has an opportunity to
- take advantage of that confusion by promoting the relative stability of the
- Macintosh platform. The fact that Macintosh today has one operating system for
- its complete product family and provides an excellent software migration path
- could be used to sway these frustrated customers and developers into looking at
- Macintosh systems.
