There might be a point in the future where Intel may decide to offer processors with HT again, but currently there are no plans for it. The reason for the lack of HT appears to be because it was a bridging technology to bring multi and dual-core to us all.
HEXUS remembers that at the time Intel were very keen to inform us that their was no cost associated with HT and it was 'free' performance. Surely it should be on all platforms still?
