Windows 7 Tip: 
Wine enables Linux, Mac, BSD, and Solaris users run Windows applications without a copy of Microsoft Windows. Wine is free software under constant development. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris.
Wine is still under development, and it is not yet suitable for general use. Nevertheless, many people find it useful in running a growing number of Windows programs.
Wine is really nice for gaming too and support some of the DirectX 9 stuff. If you check their website you’ll see a lot of popular game supported under Wine.
Wine is an excellent program for Linux, it is by far the only reason I would ever convert to Linux as a full-time OS.
I love the emulation and the fact that it shares so much support for programs that I need and use everyday.
I’ve actually been able to install much needed drivers and software to use my hardware on my PC.
Wine is a life saver, and it’s a program that all Linux distributions should and MUST have.
I will long live by Wine and support it’s advanced features.
I’m excited to see what else comes about with the Wine project. Wine is the best.
