Parallels, the popular software which allows Mac users to run Windows, Linux, or other Operating Systems in a window, will soon have a new version available. They're offering reduced prices for purchases and updates now through June 6th.
The most compelling reason to upgrade is the new support for DirectX 9.0. This allows 3d games to be run under Parallels.
Another cool feature is called SmartSelect. This allows you to associate a file type with any application installed on your system regardless of whether the application is Mac or PC based. This works with their Coherence feature which runs just the PC based application in a window without requiring a window for the Windows OS itself. This makes it appear as if the Windows applications are running natively on your Mac.
This is great news. I can't wait to upgrade so I can increase the number of games which will run on my Mac.
