I recently purchased a new HP desktop from Best Buy. The salesman was extolling the virtues of the 64 bit processor and he sold me of course, because I am a sucker for any and all technology and spending money!! He told me that the 64 bit proc was 2 processors in one and that the hyper-threading technology used by 32 bit processors was basically a "fake" when compared to the 64. What is the difference between the two? Answers coming from you guys usually shed more light than do the ones from M$ and HP.
Also, is it true that this is "new" technology and that a lot of apps aren't written yet to take advantage of this 64 bit technology?
And finally, isn't M$ releasing Vista (Longhorn) with a 64-bit OS edition?
