I installed this a few months ago so my daughter could play her favorite windows 98 games on her Macbook. It worked well but finding and installing the necessary drivers took forever.

Nearly perfect. My dream world would involve DirectX 9 support and USB passthrough support in the free version.

That said, it really does kick ass. I'd recommend it.

Sounds interesting, but Virtulization is a crowded market- Is there a guide/chart/article explaining what this offers over other solutions, such as Xen, Vmware, or Parallels?

I'm sure it's a great package, I'm just trying to find the unique selling point- I'd love your insight on what you liked about it.

For me, the selling point is the ease of use. VirtualBox is like the Ubuntu of virtualization suites... it just works, and works well, and it's easy to get going.
