This week for Siri's humor, I asked the question, "What's the best phone?". Do you really think she's going to give a different answer? It's iPhone all the way. The virtual assistant in iPhone 4S can do task like add reminders, manage meetings, and send emails for you. But that's not all. She can also engage in conversations that are not work-related. Try to ask Siri the same question and find out if she'll give you a different answer.
