“Version 4 included only rudimentary support for Windows 7, but this has been greatly improved upon in version 5. Simple tasks that worked only with older versions of Windows, or only worked intermittently in version 4, such as adding a printer, now work flawlessly,” Lu reports.
“In our tests we found that the Windows user interface felt snappier and more responsive under version 5 than it did in version 4… Parallels 5 now runs in 64-bit mode under Snow Leopard, so it can take advantage of more than 4GB of RAM,” Lu reports. “Parallels 5 is a significant upgrade over previous versions. If you frequently use other operating systems on your Mac, then the new features and improvement makes it a worthwhile purchase.”
