There is a solution for all these situations and it has been around for sometime now.
Well if you wish for the same, your wish has been granted. Games are an important mention here because although the Linux games are catching up and going 3D and stuff, one would have to admit that there are a larger number of games for Windows that keep us going back to the Windows World. It has happened to me in the past when I would switch over into Windows to play Counter Strike and Half Life and some people also wanted Photoshop on Linux because the GIMP requires some adjusting to on the interface. As much as I love Linux and Open Source, sometimes you happen to love a Windows application so much that you wonder if only this was available on Linux I would completely switch. There are thousands and thousands of applications available for Linux, and even more being developed as you read this.
