There is extensive evidence (google for that, please), that
HT is even slower than a single core in quite a few applications.
Moreover, the whole HT implementation has been shown to
be a security risk. In the near future intel is going to spend $1.9bn
on its new marketing campaign. If you wanna be part of it,
buy their CPU, half of the money will be in your nearest billboard.

Dual-core is a new, and a very smart concept, which is exactly
equal to a dual-cpu configuration in terms of performance per
core - plus it provides a huge cut down on power consumption,
and a theoretically hugely faster interconnection between the
cores (they are physically many times closer).

By 2010 we'll see 4-core, 8-core and maybe even 16/32 solutions.
