If I were in the market for a new laptop or desktop, I would be more interested in getting a 32 bit hyperthreaded processor than a 64 bit. I just received XP/64 at the office the other day and the 64bit machies are not only cost prohibitive, but there aren't any 64 bit applications that will take advantage of the processor. I'm not even going to buy a 64 bit machine to screw around with at the office for probably a few months. A hyperthreaded 32 bit processor acts like 2 32 bit processors and will give you more bang for the buck.
