I don't agree with this snippet, at least it doesn't apply to me. I bought netbook, but I wouldn't buy "real laptop" if netbook didn't exist, so no cannibalization happened. Moreover, I am not sure about that distinction. What exactly is the difference between netbook and co called "real laptop"? Missing DVD drive? Is there any principal difference? As I see it, what happened was that Asus was able to create cheap small size laptop, and many people realized that this thing is really useful.
