Hi all,
I know it has been documented previously (gQstatus05) about getting WIN7 to run in Virtualbox, but with the latest updates to
VB, it now handles the screen resizing and makes running WIN7 so much more useable, plus, it handles the sound and networking issues perfectly. You still have to edit the xml file to turn off the VT-x virtualization settings, otherwise the installation will fail, but it is ridiculously simple, and afterwards, no need to setup your Mini as a dual boot!

So far, haven't run into any snags with running both, and WIN7 is pretty snappy as the virtual OS.
