I guess I'm weird... I think the new MacbookPro's look way nicer than than the last design. I never really coveted a MacbookPro until this generation. To each his own, though.
Anyway... The MS ads aren't working for everyone. My family is in a bit of a rough patch after being comfortably middle class for most of my life. Those laptop hunters ads are targeted directly at me and my family. I'm a college student, I have to be very mindful of pricing, I'm even a girl.
Unfortunately for MS, that doesn't mean I'm a mouth-breathing deal-seeker, either. That would be my mother. (Joke!) Actually, my deal-seeking mother taught me that you get what you pay for - even SHE realizes that a "deal" doesn't necessarily mean "cheap."
Unfortunately, my mother - and most of the people these ads are targeted at - uses her chintzy plastic laptop for emailing me guilt trips and forwards of puppy photos. She really, REALLY doesn't care about a single spec. If the laptop works, and is cheap, she'll take it. End of story.
But you try to sell her a Kia, and she'll have none of it. I'm still amazed she ever bought a Hyundai.
The point is, I think everyone has that one product they will "overpay" for, because it's worth it. For most people, computers are not that product. For everyone else, there are Apple computers.
tl;dr - Microsoft's new ads will keep bargain hunters who don't want or deserve Mac's to begin with. Nothing to be concerned about.
