That's not necessarily true, HT technology doesn't give a real performance
boost unless you are running true multithreaded/SMP built applications.
Since you're using a laptop I'm pretty doubtful you're running fifty httpd
Also, HT may appear to offer you SMP, but applications may actually run
slower with SMP on an HT processor.
Multitasking different apps may get you a bit of a performance boost, but
in certainn circumstances HT will actually result in slightly slower
performance. In addition, HT on laptops is probably even less relevant
than on laptops because of the power throttling that's happening in the
SMP has problems with not only ndiswrapper, but ACPI and I've had to turn
it off whenever I install Linux on a laptop.
