Only two problems I can see.
1 It's Ubuntu
2 It's a virtual machine.
I believe it says on the link that it should
work with any OS iso, but haven't tested it myself yet. Intend to have a play when time allows, if it makes setting up VM's easier then it could be useful for checking out new distros to see if it's worthwhile burning to disc?
I agree about the VM and hardware, but I guess it's intended for desktop developers, beta testers and the curious.
