    Two cores + Hyper-Threading = Each core can process up to two threads simultaneously = Four threads in Activity Monitor

    I didn't know about that either until I observed my MBA converting a 720p video with Handbrake about 1/3 faster than my two year old iMac.

    Tech is quite amazing and so is the MBA :D
