I think the key to all the compatibility issues is buying a new PC/laptop with an OEM Ultimate pre-installed. At least most of the drivers should be certified and compatible, and then as Piper suggested, do tweaks as we find them

Its going to be a hard nut to crack, but i think soon, as more tech people jump the bandwagon and delve into the bolts of the system we'll see some good gains.

Rev, did you get your OEM version from USA? How can the pricing be soo different?
