Currently MS has stated that it will only charge a License based on processor.
I do have a question on this though.
Currently home only supports a single processor and pro supports dual processor setups.
How does this bode as the cpu go from dual to quad core (in theory should occur 18 to 36 months after dual core)
Home would in effect have to be upgraded to support even a dual core processor not to mention that it does't appear to be getting the 64 bit treatment soon.
Pro would have to go to quad support in the near future. as the number of cores in the processor goes up. or even in a dual cpu with 2 dual cores. Pro would currently only recognize the first core.
just thinking;)
