"Virtualbox is a virtualization application developed by Sun and is available for Windows, Linux, OpenSolaris, and Macintosh. It allows you to run another operating system (a guest) without dual booting. While I have always been a big fan of Virtualbox, I have always found virtualization (regardless of the application) to be slow and behind the times, so I would only use a virtual OS when absolutely necessary. Virtualbox 3.0 may actually convince me to use the technology more often.
"Virtualbox 3.0 builds upon its predecessor and includes improvements that make it a better product overall. As far as I can tell, all of the features from the 2.x series made the jump to 3.0, as well as something really exciting – 3D support for the guest operating system which means support for Direct 3D AND OpenGL! Hardware acceleration for video has always been somewhat of a sore area for virtualization. In the past, If you wanted to use an operating system specific browser or email program, then a virtual machine would fit the bill. If you wanted to use a 3D program (such as a game), you’d be better off just forgetting about it."
