Interesting point!
When the iPad was released Apple made it clear that the iPad was not a laptop replacement. Now that investrors are claiming Ipad sales are cannibalizing net book sales, I am sure Apple will nod it's head and agree that the iPad is a netbook killer.
Despite the irony of what the iPad is becoming, I am happy that Apple has become the computer maker that it could only dream of a couple of years ago. Competition is good!
Why is it a netbook killer? Why do you buy a netbook? Most buy them for the mobile computing. Mobile= email and web. Email and Web = iPad.
Plus, netbook keyboards are a joke. Putting a crippled Windows on them on that little screen that you can hardly see is a joke. They just made everything smaller with no consideration for the size and usability. I never got why you'd want one other than it was the only choice for something really small and portable. Now there is a choice and the alternative was designed from the ground up for that mobile experience. The iPad advantage.
