Bob Miksch of Seattle, an admitted tech enthusiast, has thought about all of these issues in regard to his 19-month-old granddaughter, Aurora. He summed up his perspective in an e-mail: "Play a real piano or the iPad app? When to take the smartphone away and when to allow? When to engage in five-sense activities, and when to encourage fine finesse manipulation of the ever more ubiquitous electronic controllers of our world?... We want nothing more than to equip her as best we can to help her articulate and realize her uniqueness as a living entity. Moments with her are timeless, the pleasure boundless, and while these thoughts course through my mind I simply give thanks that she is in my life."
