The hardware is impeccable, but nobody had any problem with the thickness of the first iPad and that's what they changed. They know their average consumer don't know all those things and functions like tabbed browsing, so they take advantage of it by not taking some of their time and budget to develop those functions. They take advantage of their market.
How can a consumer complain about something they don't know; they can. But they still have the right to fully understand what is available elsewhere and what functionality (that is quite crucial) they just decided to omit. Consumers have the right to know all these things.
Defending the product and just saying it is all nice and good means that it will stay that way. Criticizing and getting informed is what everyone should do in order to make good decision and keeping every new technology advanced and innovative not repetitive !
