I am a committed Mac owner and user. I just bought a new 21.5 inch iMac an am loving it. I have just become curious after having seen a whole plethora of Wintel laptops out new sporting i3, i5 and i7 processors. Taking note of some of the difficulties Apple has had in rolling out the 27 inch i5 and i7 iMacs, I'm just wondering what the story is with these laptops? How closely similar are the processors in the Wintels to the processors in the iMacs? And was Apple's difficulty in getting these 27 inch iMacs out related to the i5 and i7 processors they are using or due to a combination of other factors? I'm just kind of curious as to why the i5 and i7 rollout seemed to be such an ordeal with iMacs and seems to be happening on a large scale with the Wintel laptops. Of course I have no idea how many problems may be lurking inside these Windows laptops.
