Actually, any sort of stuttering/unusability you get from multitasking on one
CPU is because of a poor scheduling algorithm in your operating system (or at
least one that leaves room for improvement). Because HT presents one processor
as two to the OS, that scheduling problem goes away. It would not surprise me if
HT chips were dramatically more responsive (although not that much faster) when
multitasking, although I'm not saying this is a certainty. I have never used a
HT system myself.
