Bill, if one core is working for you and not giving you any trouble, go for it. My experience is definitely that a single-core Windows VM is a lot more sluggish than I’d like. It works, but it’s not at all pleasant once you start using the machine full-time, even with all the background services turned off and no antivirus. MacBook Air owners and Mac Mini users will probably all find themselves with MacBook Pros before long. MacBook Air users especially acutely because those CPUs are slow as well as dual-core. YMMV, of course.
I actually don’t like hyperthreading very much. It helps, but it does so inefficiently. The CPU is essentially cheating the OS into allowing the CPU to try and optimise workloads, but that creates an additional obligation for the OS to try to avoid allocating virtual cores that share physical cores with workloads, like virtualisation, that really need guaranteed performance. Without hyperthreading, the OS would be able to make much better guarantees about CPU resources, including some measure of “Fairness”. Of course the counterpoint here is that without hyperthreading, the CPU would often be under-utilised, regardless of whether threads had guaranteed CPU resources. So, yes, it probably had to happen. The workarounds to the workarounds were developed, and we all lived happily ever after. -- The following information is important for all members of the Mac Visionaries list.
