I regularly hook up my toys in a veritable spiders web of wired and wireless connections to perform various functions. Has anyone discovered more possibilities? Here's the kind of thing I mean. Starting from the iPhone connected to the Internet via 3G, I plug in a set of speakers to the headphone port, so I can get some sounds going. (Having played with a Bluetooth speaker bar, I'm tempted to blow the $400 to acquire one.) Next, I tether the iPad to the iPhone in order to give me Internet capability on the iPad without having to buy a separate data plan. Then comes the wireless keyboard connected to the iPad via Bluetooth. With everything plugged in and ready to go, I can sit back with a can of beer, and unleash a torrent of emails on an unsuspecting world. Can't wait for iCloud to further enhance the experience.
