Mac OS is awesome, however there are a lot of softwares that only available in Windows. When this happens you have to switch back to windows computer. Or else, you might have used bootcamp to installed Windows OS in your computer. However, using dual OS it means that you have to restart your computers to switch to the other OS. This is very painful. I have this experience using Ubuntu. After a few months, I gave up and use Windows only. However, now with Parallels Desktop, everything becomes so awesome.
This is my desktop. You can see that I am running TVU player’s windows version and ShareInvestor Station side by side in Mac! All the windows application becomes just like a normal application in your mac. So you don’t have to restart your computer to access the windows applications. This is just awesome. However, the Parallels Desktop will allocate a certain amount of CPU and memory resources for Windows.
