    Does said technology exist/work with a Core 2 Duo? It'd be awesome to virtualize 4 cores.

    HT was dropped during C2D's development, I believe it is being reintroduced in i7 though isnt it? Frankly it was developed to help stave off Netburst (early P4)'s big weakness which was its extremely long pipeline that caused it to lack performance per clock. HT allowed instructions to be run out of order to keep things moving along better when several programs needed simple computations done at the same time. With C2Ds massive improvement in floating point power it became essentially unnecessary, and those chips were basically just a heated up and reworked P3 architecture so they lacked development for HT support natively anyways, Intel needed an answer to AMD's Athlon 64 fast so they just made P3 into a new age beast and got back where they needed to be while they developed a follow up.

    Well, in layman's terms, a Core 2 Duo CPU simply does not know what Hyper-Threading is.

    Hyperthreading will be back with Nehalem processors on the Calpella Platform this fall. Also Atom has it.

    HT made a comeback in the Intel Core i7, although that's for the desktops. So nope, no HT for us notebook people xD
