To be fair to Intel, HT is not an actual bad idea, just a bad 
implementation on top of a bad architecture.

The HT-like model is also used SUN's T1 processor, giving up to 4 threads 
per core. It is actually a clever solution to make use of ALU units that 
would otherwise be idle due to pipeline stalls. And Netburst had lots of 
stalls!

I share most of your anti-Intel sentiment, however:)
