Surely those guys are hyper-threaded by now ? at least the Atom
(which is cheap as chips [sic] ;-) is.
I recognize this comment was in gest, but thought I'd chime in with a
tidbit. I believe that Intel removed HTT after the Pentium 4 chip.
Of note, as well, is that hyperthreading (HTT) is not as "universal"
an upgrade as true multi-core chips. In fact, the general practice in
the High Performance Computing (HPC) community is to turn off
hyperthreading because it degrades performance for most workloads.
A further note is that there is some skepticism as to the security of
HTT, in terms of side-channel monitoring of in-core process data.
Actually, now that I just wrote the above, I seem to recall a
discussion of HTT technology in the Nehalem chip. When I have time, I
might research that ...
Cheers,
Kevin

Kevin you are right the current i7's support HTT. It has come back with
a vengeance. the i5's and the i3's don't support hyper threading.
