The specs of the virtual machine are
Core 2 quad (2.4ghz) (2 processors)
1 gb Ram
30 gb HDD
To be honest it's much better than vista although i couldn't use the dedicated video card in it since the virtual machine used it's own graphic accelerator. But otherwise it's very stable and great performance .
In short, it's vista with some polish and excluding all the bugs in vista. I'll definitely be making this my primary OS once the full version is out . Currently i'll have to live with vista
