Hi,

sorry for taking over this thread.
I know this is sort of OT but I don't quite understand the topic.

Does this all mean
a) it is no advantage for PD to run with/on a Core Duo processor (on 
WinXP or linux)
b) it is a disadvantage
c) it is a disadvantage unless I deliberately make _no_ use of the 
virtual multiprocessor?

If this thread isn't related to Core Duo then I'd appreciate any 
comments on my questions (since I'm trying to find the right "next laptop").

Thanks
Urs
