Parallels continues to rock the Apple world. After its recent announcement that the company has surpassed selling 1 million copies of the Parallels Desktop product, this virtualization company is still moving quickly to try and capture even more of the Mac market.

Parallels is now up to Beta4 on its anticipated server virtualization product. With build 1990, the company has re-introduced Leopard Server virtualization support back into the product - meaning that you can once again run Apple's Leopard Server in a virtual machine on an XServe running Leopard Server. In addition, they've improved the virtualization engine for added performance and machine density, enhanced the networking performance and updated the user interface.

At the same time, a partnership between Parallels and Microsoft is allowing for the Parallels Desktop for Mac product to become a part of the Microsoft Expression Professional Subscription. The company says this will allow millions of designers using Mac computers to use Microsoft's Expression Studio to design desktop and web-based graphical interfaces. The partnership also provides an even deeper support level from Microsoft for Microsoft Windows and Microsoft applications running in virtual machines.
