And that's probably part of what's happening at Apple as well ? We've seen important, but not quite groundbreaking products get left for dead, and eventually killed when at Apple's size it probably wasn't that problematic to keep them alive. I'm thinking about their network router lineup for instance. Or how nobody cares enough to make a Calculator app for the iPad.

Supposedly Steve Jobs hated every iteration of the calculator on the first iPad, so they just didn't ship it at all. Might just be tradition at Apple to not touch that topic.

Google pays over $300k a year for many of their engineers, and Apple pays quite well too. Regardless of how easy that calculator app is, it'll take a team of people to build, and that team is expensive, like millions of dollars expensive, and it'll never be worth it.
