When you use a real time operating system it schedules event in a predictable way. Normally a computer manages the load and just does things as fast as it can. So when you run an application it my take 1 second to do an operation and 2 second the next time. I just use seconds as an example chances are operation are going a lot faster then that. With a real time operating system it will take the same amount of time each time you do it. This is important for timing when dealing with some events. This is a good write up

Most of the time we will never notice the difference when using normal applications. Here are a few examples

Linux:

some info on Solaris

Not knocking windows just don't know what options they offer. In reality unless you are dealing with very fast events chances are your applications will work just fine. For example the rate you type no matter how fast you go is slow compared to your systems ability to process the input and put it on the screen.

Real time = things happen as fast as you need them to.

Windows standard, no, Windows CE, better.
