I was talking to my mom today (a proud senior-citizen iPad owner) and she asked me a question I didn't really have a good answer to: "What are they going to put on the next iPad?" I started out by reminding her how the original iPod had progressed, from a simple device to play music, to adding a calendar and notes, to pictures, then videos, and then finally e-mail, the web, and Apps. But the more I talked, the more I realized I don't have a very good answer as to what they are going to do with the iPad. I'm sure that, qualitatively, the iPad will continue to improve. It'll get faster processors, more memory. It might (unlikely) get lighter and slimmer. It may very well get a higher-resolution display. But its already got a camera, speakers, all sorts of sensors. Its got the web, and e-mail, and half a million Apps. Those things might get better - but I'm struggling to see a clear way for Apple to add a quantitative new functionality to the iPad. About the only way I can see to add a quantitative functionality to the iPad, is to expand the universe of digital, electronic, and physical things the iPad can connect with. The iPad as a mega "remote-control" for your TV set and your HVAC. Your car and your sprinkler system. What is the future path for the iPad? I'll turn my "skeptic" meter off - all suggestions are welcome, no matter how outlandish they may, at first, appear.
