Decided to throw an earlier build out of the VM and install the official beta as a dual boot system. The only thing I was unhappy about during the install were a couple of periods of apparent inactivity, just the background screen and no disk activity, but it carried on after 5 mins or so.
Starts up quickly and seems to be stable. the main problems seem to the lack of drivers other than the bare bone ones that MS supplies, I can't install the Nvidia drivers from Nvidia as it says it's Un-reconized operating system. So until the OEM people update drivers some limitations will be obvious.
