This is interesting and it just goes to show that when given the option of two products, consumers won't always necessarily choose the cheaper one, even in a time of economic trouble. Apparently, more netbooks were sold this past summer than iPhones, by a significant margin.
A report at jkOnTheRun shows that when you take into consideration all netbooks sold, the total comes to about 5.7 million units. However, the iPhone only sold 4.7 million units. All of this even though the iPhone is cheaper than netbooks.
This seems to indicate that the netbook market is growing must faster than the iPhone market did, and while consumers that buy either product might be after different things, this data shows users want a complete computing experience for cheaper. Not a mobile device that offers a bit of luxury.
