Revolution and innovation don't happy everyday, that's what makes them special and amazing. Expecting one company to be revolutionary and innovative once a year is expecting too much, once every ten years is probably expecting too much. Good incremental steps is not only expected, it's probably all that's possible.
Most people go through their entire life without thinking up something innovative, much less making it.
True. Nonetheless, I find myself a bit disappointed. At this point, the only thing iPad has is a first mover's advantage aka the App Store. There are very compelling alternatives available in both 7 inch and 10 inch range with interesting experimentation - Surface Blades for example. Nexus 7, Lumia 2520, Surface can match the build quality.
