To me, the purchasers of netbooks and the purchasers of MacBooks seem like different markets. Netbook people were already looking for a $600 laptop for doing basic tasks. They're happy with a basic machine for surfing the web. People who buy a MacBook are a little less price sensitive and more style conscious. Maybe they're into more media related stuff.

I know that NYC, where I live, isn't necessarily representative of the world as a whole, but when I go to Starbucks, the only people with tiny laptops are Japanese girls. Businessmen have Lenovos and Dells, and everyone else has a Mac.
