I think when they raise Clockspeeds in Dual Cores it would be great. I mean the 840 has the speed, but only because it has HT. The others drop way below any normal Processor like a 620 or 540J even because of their dreadful Clockspeed.
Until then, HT will do any Home User perfectly fine for Multitasking.
