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 ...
