I have been reading on the forums quite a but lately, and I have noticed some people are saying they are waiting for a Quad-core MBP and to skip the i5 & i7. I am confused. I thought th i5 and the i7 were both quad core with th i7 having hyperthreading. Is that wrong, or is my i5 actually a dual core, even tho running my cpu monitor gadget in Vista (ugh) says there are 4. I'm so lost.
