Bluetooth 4.0 also, ironically, even simplifies the connection of Wi-Fi devices. Right now, adding a Wi-Fi gadget often requires users to hand-enter configuration information. To oversimplify, Bluetooth 4.0 enables new Wi-Fi devices to get configuration information automatically; instead of asking the user, Bluetooth 4.0 enables devices to communicate configuration information with each other. The only user involvement required is permission.

What devices will the iPad connect to via Bluetooth 4.0? Well, just about everything Apple makes, for starters. Apple's iPhone 4S supports it. So will the company's full line of Macs, from the MacBook Air to the iMac.

I also believe all future versions of , as well as the rumored Apple TV set, will support Bluetooth 4.0. Most Apple pundits, including me, believe Apple will use Siri (when it's ready) to control TV.

I believe Apple's TV-controlling "breakthrough," suggested by the late Apple founder Steve Jobs in his recent , involves voice commands, but via any Apple device. I predict that Apple TVs will come with a remote that has a microphone. You'll tell Siri what you want to watch or record, and Siri will do your bidding. But this same functionality will almost certainly exist in iPhones and iPads. Just tell your iDevice what you want to watch, and Siri will make it happen.
