WARNING: Version 2.5.3150 is a "Release Candidate." It's not a final, stable version. If you want a more stable build, visit and download build 1970: http://www.parallels.com/en/download/desktop/

That said, version 2.5.3150 is a much more stable and less buggy than the previous release candidate, which really should have been labeled a regular beta test program.

Parallels is stable, the coherence feature makes switching between both OS X and Windows a lot more streamlined. I just wish that ArcGIS and GPS software are available for OS X so I wouldn't need something like this in the first place, but thank goodness Parallels is able to fulfill this need.
