We got a quick demo of the new app, and it looks great -- Parallels has expertly integrated Windows and OS X in whatever form you want, from a full screen switchable setup, to a windows mode, all the way to Coherence mode, which leaves the virtual machine metaphor out of the equation and just lets you run Windows apps straight from the dock as if they were Mac apps.
There's one caveat: Parallels has discontinued support for Tiger, so you'll need to have OS X 10.5 or better installed to run Parallels 6. The app comes in two flavors: Parallels Desktop 6 is the standard app and can be purchased (officially starting on September 14th, we're told, regardless of what's on the shelves at your local Best Buy) for US$79.99, or you can get a Switch to Mac edition (which includes easy file migration and special tutorials for Mac newbies) for $99.99. Previous users of the software can get an upgrade for $49.99. Stay tuned, too -- Parallels tells us it has more even more big news about the new version coming up soon.
