hi,
The people I have spoken to who use PC's are not nerds or power users, however, they do have monitors that work perfectly fine and want to use them. Why would someone purchase a 20" iMac when they already have sitting on their desk a 12 month old 19" LCD? They may not all need expandability (or really understand what that means) but they are of the mind set that they must have the option. These people are simply not considering Apple computers because of the lack of an upgradeable computer that is under $1500 (the mini is not easily upgradeable unless you happen to be one of those nerds you are refering to). The gap between the mini and the Mac Pro is enormous in both power and price yet there is nothing in the middle price/power range. Simply dismissing this catagory of people will not convince them to buy an iMac. Further, saying the operating system will convince them to switch is a moot point if they never buy the computer in the first place.
My friends, family, and co-workers are all interested in this "OS X thing" but get turned off at the price of the Pro, the lack of power of the mini, and the all in one of the iMac. This is what I am seeing, and Apple is losing sales because of it.
