Khoi Vinh wrote a thoughtful analysis on the future role iPads (and other tablets) may play in our lives:
Traditional publishers are pouring millions into establishing a beachhead on tablets and e-readers, perhaps with good reason. But the intense competition and experimentation (much of it misguided) is almost assuredly unsustainable; almost all of the content apps that we see today will be gone within a few years, I predict, or they will be supplanted by browser-driven editions as their native iOS or Android apps prove too expensive and impractical to maintain.
What’s more, all of these efforts conform to a familiar pattern: at the start of nearly every technological shift, legacy brands manage to command a disproportionate amount of attention as they attempt to stake their holds in the new space, but almost always find themselves unable to sustain that attention through genuine innovation. Ultimately, it’s the pure play companies that realize the medium’s true potential.
