Double bonus the new version has support for taking full advantage of i5 and i7 procs, and I'm running an i7 920. Time to upgrade when I get home tonight.
I personally use VMWare Fusion for reversing Windows executables, VMs are invaluable in that snapshotting aids in quickly returning to a known good state, and I can continue to take notes in applications outside of the VM to keep track of my progress.
I fear most for OpenSolaris. It's harder to fork than VirtualBox and far bigger.
I particularly love ZFS and its Linux-ish the package management.
They could have the latest Gnome desktop for the adventurous ones.
"Mac OS X verifies whether it is running on Apple hardware, ...these restrictions are not circumvented by VirtualBox and continue to apply."
Wonder how long until someone patches the source to remove this check. A guest OS shouldn't be able to snoop and find out what kind of hardware the host OS is running on...smells like a hack.
This is the basis for the "hackintosh"
I'd hazard a guess that it would be pretty easy to get this going on VirtualBox using iBoot + Multibeast.
"Even when idle, OS X guests currently burn 100% CPU. This is a power management issue that will be addressed in a future release."
:(
Hope this keeps up.
