Yes. The only way that with hindsight it will not seem out of proportion, is if it really does end up significantly altering the way we interact with certain sorts of computers, and makes a success of the tablet form factor.
Even if it fails massively I consider Sunrays notion that it is nothing more than a blip on the sea of netbooks to be very silly- even if it fails it will be a huge story and could be an important nail in the coffin of the tablet formfactor, or would have implications for Apples methods of control and app store etc.
Another reason not to compare it to a netbook is that there is a proven market for those that is quite large, not so for tablets.
All of the above.
