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 😀
