"No wireless. Less space than a nomad. Lame."

7 years later when we look back, it look like iPod team really just worked on some consequential features. But at the same time, how do I know what I am working on is not inconsequential features?

Get the thing in front of users. Usually this means launching, but it could be enough to use what you're making in-house.

But how do you filter out what those users exactly want from noise? For example, a lot of users making noise to Apple saying they want FM radio, wireless feature. Apple did not put the wireless until iPod Touch and iPhone. And still no FM.

The filtering is based on data? or vision?
