In the “faster” category, Parallels Desktop 5 now includes full Aero support in Windows Vista and Windows 7, and an improved Parallels Transporter promises to speed up and ease the task of converting a standalone PC into a Parallels virtual machine. Version 5 ($80 upgrades, $50) includes more than 70 new features targeted at making the program faster, smarter, and more powerful. Parallels Desktop 5 works in both Leopard and Snow Leopard. The latest release of the virtualization solution allows users to run Windows, Linux, and other operating systems on their Intel-based Macs.
