If you look @ the prelaunch iPad press, there's lots of people predicting failure for the iPad, "oversized iPod touch", "useless" etc.
Whereas a car thats just like the other car, but much cheaper is I'd say a no brainer,
Apple put some thinking, bucks and technology into launching the iPad, and when you risk tons of $ into developing a product existing laws allow you to protect your IP investment.
As an owner of a pre iPad tablet, yes the iPad created the iPad and post iPad tablet market "100% and completely". If you disagree I'll accuse you of either intellectual dishonesty or cognitive blinders.
The iPad is more than fender flares and a V8 in a car. A mustang does exactly what other cars did before it.
iPads do things right now that no tablets ever did. Light, 8-10 hr battery, finger, etc.
They are arguing that the other tablets shouldn't exist because they look like iPads - but as that idea wasn't Apple's (all tablets look the same), they shouldn't be allowed to. And whether they created the market or not is also irrelevant - you cannot sue under patent law for that.
