I believe they might be "real" shoppers...
I can fully believe that they are "real" shoppers, and not just actors paid by MS to say what they want to say. Having worked selling computers, the problem is that most people just look at the price tag of computers, and not what they'll actually DO for them. So many times I was selling a customer a computer and asked them if they've considered a Mac, only to have them say no, they're too expensive. When you take time to show them a Mac, explain the differences and how they can be better, some people would actually see the value in what they're spending all that money on and buy a Mac.
A big problem in the Mac world is that not many computer sales persons actually KNOW anything about Macs, so are reluctant to sell something they don't know much about. You also have so many places on commission, with incentives and bonuses to sell product A over product B, and it is hard for a customer to get a true, honest opinion on products. I've walked into a computer store near where I lived, told them I want to buy a Mac, only to be "sold" an HP laptop. Was it the best one for me? No....I got the feeling the sales guy didn't know much about Mac, so didn't think he could sell the product....who knows, maybe he got more of a bonus off of the HP as well....
Lastly, the thing that makes me laugh is that the people state what they're looking for, and yet don't look at the good features that the Macs would give them. Look at the video editor....what person that does any editing or creative work doesn't know that Macs are great for that sort of thing? While the price of a Mac doesn't always fit into everyone's budget, for most of the shoppers they could have found a Mac that would have fit their budget, and fit their bill. The only problem Mac has is that most of their "consumer" level laptops are only 13" screen sizes...one of the big reasons why most people who I was selling laptops to DIDN'T buy a Mac... they wanted a 15-16" screen size. If Mac made a 15" Macbook that was only SLIGHTLY more than their 13" version, perhaps spec. it the same as a 13" with a bigger screen I think you'd find more people interested in buying. I personally spent all that extra cash to get the 15" screen on my MBP... I have yet to use the fancy extra GPU that it came with, but really wanted the bigger screen.
All in all I think the Hunter ads are effective at getting the message across to their perspective customers, but think it is funny how the MS ads don't actually sell their product directly....HP, Dell and all the other computer makers must love the extra advertising. Mac's ads are still the best in my mind...hey, they actually address their product, but good job by MS in my mind.
