The three operating systems can all offers a lot to the users. They are definitely much powerful than the traditional DOS for PC machines and let users have more control over the usage of their CPUs.
We have already summarized the main features of each operating system and briefly compared each of these operating systems. It is not hard to see that there is a lot of common grounds between these three operating systems, however, each has its own strengths and weaknesses. OS/2 Warp Connect and Linux are so far the best in its technical advance, however, with the shortage of software suppliers that supply programs for these two operating systems, users may find some limitations. Windows 95 still needs great improvement in its memory management, and base architecture, but it has many software companies backing it.
Hence, if you like the robustness and the object-oriented design of the operating systems, OS/2 Warp is the way to go. If you are a scientist and would like your work to be compatible with other UNIX systems, Linux is a good choice, plus you can get tons of free software. However, if you want to keep up with the new software that come out of the market, go for Windows 95. The conclusion is: It all depends on what you want to do.
