Thanks to WINE and its commercial big brother, CrossOver, you can run some popular Windows programs on Linux.



From ZDNet:

There are two basic ways to run Windows programs on Linux. One is to use CodeWeaver's CrossOver Linux. This program enables you to run many popular Windows applications on Linux. Supported Windows applications include Microsoft Office (from Office 97 to Office 2010), Internet Explorer 8, all current versions of Quicken up to 2014, and some versions of Adobe Photoshop and Photoshop CS.
