One thing that gets my goat is inaccurate computer reviews.
For example in this weeks Shortlist (Free magazine handed out in Birmingham and other big cities)
they reviewed a Toshiba A665 laptop:
"The Intel i7 is the most powerful processor you can buy and uses Hyper-Threading to boost the power, when necessary, to a scorching 2.93GHz."
While it is true that the processor does indeed have a function to boost CPU speed to 2.93GHz this function is called Turboboost, Hyper-Threading is a feature that make one physical CPU core appear as 2 virtual cores.
