So far so good with this developer build of Windows 8 64-bits.
I installed on my MSI MS-1013
. The installation went without a hitch. Surprisingly even with the Microsoft Basic Display Adapter - yes, I could find any driver that would support the ATI Xpress 200M on this baby, though there was no issue with Windows 7 64-bit Ultimate - resolution was set at 1024 x 768 but the internal LCD presents itself like 1200 x 780 (amazing) and very clear.
Firefox Nightly Build runs smoothly. Apart from the shutdown and restart button now hiding away within the Settings of the Metro Menu (one can also use Ctrl-Alt-Del) I see this as a keeper til now.
As virus scanner I use the standard free and reliable Microsoft Security Essential. More to come.
