From the linked article:
Although the MacBook Air is much more expensive than many mainstream laptops today, other vendors will respond in a similar way and create thin-and-light designs to take on the MacBook Air, but with cheaper prices. The MacBook Air represents the future of all laptops, but it may take a while for the rest of the companies to catch up.
This is EXACTLY what I've been saying. Apple has re-invented the netbook market with the 11" in particular. And perhaps the ultra-portable market with the 13" MBA. I keep getting all sorts of flack for referring to the 11" MBA as a "netbook" but it IS and it will now DEFINE the netbook market for 2010 and forwards. You can't compare Apple's product introductions to prior generations of competing products. That's not how they operate. They don't make "ThinkPad" rivals, they instead invent new market segments with slightly differentiated product, often using legacy technologies. They've done it before and they are doing it again.
People who keep claiming that I'm denigrating their Mac Netbooks by calling them as such are stuck in 2007/2008 mindsets. Anyone who has been keeping up with the tech industry knows that the Netbook market, which has all but driven the PC and Windows growth for the past 3 years, has stagnated and reached a plateau. The iPad proved that the market was ready for a better netbook and the 11" MBA demonstrates that Apple's view of "Netbook" is expansive and encompasses new turf and capabilities that Asus and others could not.
What you'll start seeing, and my guess is within months of this post, is a whole slew of 'premium netbooks' designed to compete with the 11" Air. And that's saying a LOT for a company like Apple that still holds a minority market share position of the PC market.
