I have over six pages of apps. I can check Facebook, the Stock Market and the weather in Paris. But the thing that used to be my phone's primary purpose -- before it became so smart -- is the most underused app of all.
Tom doesn't have a land line. If I want to reach him, I can try his cell. But it usually goes right to voicemail. I can try emailing him at one of his four hundred email addresses. Or I can text him. He responds promptly to texts. Except when he doesn't.
