Oh I think we have a Windows user here.
Yes, when you use Windows it's wise to have two processors so one can run an
infinite loop on a broken part of the OS while the other one can still be
useful, running scandisk and downloading the latest MS security patch.
But maybe you could just switch to a reliable OS like Linux and then you could
afford to run a single processor computer?
