The iPad reviews are similar in that they focus on the “missing” features. Those missing features are typically available in a variety of unsuccessful competing products, which leads people to erroneously conclude that a successful product would necessarily have even more features!
I believe this “more features = better” mindset is at the root of the misjudgment, and is also the reason why so many otherwise smart people are bad at product design
Pick three key attributes or features, get those things very, very right, and then forget about everything else. Those three attributes define the fundamental essence and value of the product — the rest is noise.
