I agree with Beeblebrox. These kinds of arguments always leave out the obvious. Some people buy a computer based solely on price.
I had a friend in college that's a good example of this. She was a communications major. (she did not use computers on a daily basis) When it came time for her to buy a computer she only looked for a laptop that costs $600 or less. She's the type of person that doesn't know what 802.11n is, nor does she care. She wants to be able to access YouTube and write her class assignments. To some people specs do not matter! Price is their only criteria.
